In the title compound, [Pt(C10H8N2)(C11H11N2)2](ClO4)4, the square-planar PtN4 coordination geometry is slightly deformed, with the coordinated N atom of one of the N-methyl-4,4′-bipyridinium (MQ) ligands 0.262 (8) Å out of the plane defined by the rest of the coordinated N atoms and the Pt atom. The exceptional behavior of this MQ ligand is interpreted in terms of the electrostatic interactions between the positively charged MQ ligands and the perchlorate anions, where the N(MQ)...O(perchlorate) distances are in the range 2.932 (12)–3.259 (13) Å.

Comment top

We previously reported that amidate-bridge PtII dimers with a general formula of [Pt2(NH3)4(µ-amidato)2]2+ (amidate = acetamidate, α-pyrrolidinonate, α-pyridonate, etc.) serve as effective H2-producing catalysts in a well known photosystem consisting of edta, Ru(bpy)32+ and methylviologen (Sakai et al., 1993) (methylviologen = N,N'-dimethyl-4,4'-bipyridinium dichloride). Up to now, a large number of mono- and dinuclear PtII complexes have been prepared by us, and their catalytic activity has been evaluated based on the amount of H2 evolved under visible-light illumination (unpublished results). Consequently, we recently found that mononuclear PtII complexes of N-methyl-4,4'-bipyridinium (MQ), such as the title compound, (I), exhibit relatively high catalytic function compared to the common mononuclear platinum(II) complexes. We report here the crystal structure of one of such complexes prepared in our laboratory.

The asymmetric unit of (I) consists of a mononuclear PtII complex cation and four perchlorate anions. The stereochemistry of the Pt ion can be described as the N5 atom is shifted by 0.262 (8) Å from the Pt coordination plane (N1–N3/Pt1) defined by the remainder of the coordinated N atoms, including the Pt atom, where the four-atom r.m.s. deviation in the mean-plane calculation is 0.0181 Å. This is not only due to the relatively strong intermolecular π-\-p-stacking interactions achieved between the bpy ligands (see Fig. 2), but also due to the fact that the positively charged MQ ligands have strong electrostatic interactions with one of ClO4 ions (see Fig. 3). The strong interactions between the MQ and the ClO4 ions can be understood by the following contacts: O10B—N6 = 2.932 (12) Å, O11A—N6 = 2.996 (12) Å, O10B–N4i = 2.998 (12) Å and O11A—N4i = 3.259 (13) Å [symmetry code: (i) x, y, z − 1]. Two pyridyl units within bpy are twisted by 7.7 (5)° to each other. The bpy plane is canted with respect to the N1–N3/Pt1 plane at an angle of 3.8 (3)°, which is also relevant to the intermolecular associations achieved in the crystal. On the other hand, the pyridyl ligands derived from MQs (which are bound to the Pt atom) are largely canted with respect to the N1–N3/Pt1 plane [75.8 (2)° for the pyridine involving N3 and 75.6 (2)° for that involving N5]. The dihedral angle between the two aromatic rings within each MQ is 47.5 (2)° for the MQ involving N3 and N4, and is 42.9 (2)° for that involving N5 and N6.

The shortest Pt···Pt distance is 7.9822 (6) Å, confirming the lack of any Pt···Pt interaction in (I) (see also Table 1). As shown in Fig. 2, the cations are arranged in a stair-like fashion to give a sort of one-dimensional π-stacked array. An inversion centre is located at the mid-point of a geometry where a ππ stack is achieved. The N1/C1–C5 ring has a π-stack to the neighbouring ring through an inversion centre, where the average plane-to-plane separation is estimated as 3.469 (6) Å. The N2/C6–C10 ring is similarly correlated to the neighbouring ring through an inversion center with the average plane-to-plane separation of 3.574 (17) Å.

Experimental top

N-Methy-4,4'-bipyridinium perchlorate used in the following synthesis was prepared as follows: a solution of N-methy-4,4'-bipyridinium iodide (3.4 mmol; Van Emon et al., 1986) and AgClO4 (3.5 mmol) in water (10 ml) was heated in the dark at 333 K for 2 h, followed by filtration while it is hot for removal of the AgCl precipitated. Leaving of the filtrate at 278 K overnight afforded the perchlorate salt of MQ as colorless needles, which were collected by filtration and air-dried (yield: 78%). The purity was satisfactorily confirmed by 1H NMR.

Compound (I) was prepared as follows: a solution of PtCl2(bpy) (0.10 mmol, 0.042 g; Morgan & Burstall, 1963) and AgClO4 (0.20 mmol, 0.042 g) in water (20 ml) was refluxed in the dark for 2 h. To the solution was added N-methy-4,4'-bipyridinium perchlorate (0.20 mmol, 0.054 g) and the mixture was further refluxed for 4 h. After the AgCl precipitated was removed by filtration, the filtrate was evaporated to a total volume of about 5 ml until a small amount of yellow precipitate started to deposit. To the solution was then added 2–3 drops of an aqueous saturated sodium perchlorate solution. Leaving of the solution overnight afforded (I) as a yellow precipitate. The product was finally recrystallized from hot water to give the final product as yellow needles (yield: 67%). 1H NMR (D2O, 296 K): δ 4.30 (s, 6H), 7.47 (m, 2H), 7.60 (m, 2H), 8.07 (d, 4H, J = 6.80 Hz), 8.26 (d, 4H, J = 6.80 Hz), 8.81 (d, 4H, J = 6.80 Hz), 9.22 p.p.m. (d, 4H, J = 6.98 Hz).

Refinement top

For two of four ClO4 ions, O atoms (O9—O16) were treated as being disordered over two sites. For each disordered anion, isotropic displacement parameters of O atoms were defined with a single free variable. In either case, the occupation factors of two sites were refined to reveal that they were equally populated. As a result, their occupation factors were all fixed at 50%. In the refinement of these disordered groups, the Cl—O distances were restrained at 1.43 Å and six O···O distances within each perchlorate ion were restrained as equal. One of the remaining ClO4 ions was also judged to be partially disordered, in which only one of four O atoms was assumed to be disordered over two sites (O8A and O8B) with 50% population each. Since a void problem was suggested by PLATON (Spek, 2003), an O atom was located and refined isotropically assuming the presence of a water molecule. However, the occupation factor of the atom converged at 18 (1)%. Moreover, the difference Fourier map without locating this atom did not show any sufficient electron density around the geometry. Finally, we decided not to locate any atom around this void geometry having an estimated volume of 41 Å3. All H atoms were located at their idealized positions as riding atoms [CH(methyl) = 0.96 Å and C—H(aromatic) = 0.93 Å]. In the final difference Fourier synthesis, 6 residual peaks in the range 1.17–2.53 e Å−3 were observed within 1.08 Å from Pt1.

Experimental. The first 50 frames were rescanned at the end of data collection to evaluate any possible decay phenomenon. Since it was judged to be negligible, no decay correction was applied to the data.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Rms deviation of fitted atoms = 0.0154

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
