The performance of a Fresnel-type compound refractive lens for focusing cold neutrons was evaluated. The lens consists of 44 pieces of compound Fresnel-type refractive lenses made of MgF2 single crystals. The intensity profile of the diffracted neutrons measured over the wavelengths of 9-14 Å was compared with the results of numerical simulations. Good neutron transmission of 0.85 for 9 Å neutrons and a focal length of 3.4 m for 16 Å neutrons were achieved.

The mol­ecule of the title comound, [Cu(C36H20N4)], is not entirely planar in the crystal structure (i.e. not D4h), but is slightly deformed, with only Ci symmetry. The mol­ecules are stacked along the b axis in a herring-bone fashion.

In the title compound, C44H38N4·3C7H8, the porphine (CP) is a soluble precursor of metal-free porphyrin which exhibits an excellent field-effect transistor characteristic. The CP mol­ecule is not entirely flat in its crystal structure (i.e. not D2h), but is slightly deformed, as characterized by crystallographic Ci symmetry. The geometric isomer of CP could not be identified due to orientational disorder.

In the title compound, C44H38N4·2CHCl3, the porphine (CP) is a soluble precursor of metal-free porphyrin which exhibits an excellent field-effect transistor characteristic. The CP skeleton is entirely flat and characterized by crystallographic Ci symmetry. In the present geometrical isomer, the C-C single-bond linkages of the four peripheries are arranged in an above-above-below-below manner with respect to the CP skeleton.

The asymmetric unit the title compound, C18H16N4O3S·2C3H7NO, contains a mol­ecule in a zwitterionic form with a deprotonated hydroxyl group and an iminium group, and two dimethyl­formamide solvent mol­ecules. The dihedral angles of the guanidine group and the naphthyl ring system with respect to the central benzene ring are 76.04 (7) and 3.45 (9)°, respectively. The conformation of the mol­ecule may be influenced, in part, by two intra­molecular hydrogen bonds, while in the crystal structure, inter­molecular hydrogen bonds form one-dimensional chains along [010].

In the title compound, [CoBr2(C14H24N4)]·Br, the CoIII ion is located on an inversion centre and possesses a distorted octa­hedral coordination geometry in which four nitro­gen donors of the ligand mol­ecule are in the equatorial plane and two Br- ions occupy both the axial sites to give a trans isomer. The Br- counter- anion is also located on an inversion centre.

The title mol­ecule, C17H13N5O4S, has a trans configuration with respect to the diazenyl (azo) group. The pyrimidine ring and the terminal benzene ring are inclined at angles of 89.38 (4) and 1.6 (6)°, respectively, with respect to the central benzene ring. The conformation of the mol­ecule is in part stabilized by an intra­molecular O-H...O hydrogen bond. In the crystal structure, mol­ecules related through inversion centers form hydrogen-bonded dimers involving the sulfon­amide N-H group and the N atom of the pyrimidine ring.

A dinuclear palladium(I) complex bridged by two diphosphine ligands, bis[[mu]-methylenebis(dicyclohexylphosphine)- P:P']bis[chloropalladium(I)](Pd-Pd) diacetonitrile solvate, [Pd2Cl2(C25H46P2)2].2CH3CN, has been prepared, and the crystal structure determined. The two, approximately square-planar, ligand arrays show twisting, and the torsion angles are interpreted in terms of the steric factor between the diphosphine ligands.

In the title compound, [Ru(C10H8N2)2(C21H18N4O4)](PF6)2, the RuII complex cation reveals a slightly distorted octa­hedral coordination. The coordination bonds of the 4,4'-substituted bipyridyl donors [Ru-N = 2.038 (3) and 2.051 (3) Å] are shorter than those of the 2,2'-bipyridyl donors [Ru-N1 = 2.065 (3)-2.077 (3) Å], due to the electron-withdrawing effects of the substituents at the 4,4'-positions. The angles between the pyridyl planes of the three bipyridyl ligands are 1.5 (2), 6.3 (3) and 8.7 (2)°, respectively. The cations are connected by anions via N-H...F inter­actions.
