In the title mononuclear complex, [Cu(C11H7O2)(NO3)(C10H8N2)], the CuII atom is five-coordinated in a distorted square-pyramidal environment by two N atoms of 2,2'-bipyridine, two O atoms of 1-formyl-2-naphtholate and a nitrate O atom. Mol­ecules are stacked by [pi]-[pi] inter­actions [the dihedral angle, interplanar average distance and ring-centroid separation involved in stacking are 0.000 (1), 3.3504 (2) and 4.0800 (7) Å for stronger inter­actions, and 2.505 (1), 3.5373 (2) and 4.2048 (9) Å for weaker inter­actions] into a one-dimensional structure.

The title compound, [PtCl2(C15H20N2S)], was synthesized from the reaction between N-heterocyclic carbene(NHC)-thio­ether ligand and potassium tetra­chloro­platinate. In the crystal, the mol­ecules are linked via C—H...Cl and C—H...π inter­actions, forming a layer parallel to the ab plane.

The title salt, [K2(C16H12O6)]n, was obtained by the reaction of 1,2-bis­[4-(ethyl-carbox­yl)-phenox­yl]ethane with KOH in water. The anion lies on a crystallographic inversion center, which is located at the mid-point of the central C-C bond. The K+ cation is coordinated by six O atoms, two from the chelating carboxyl­ate group of the anion and four from four neighboring and monodentately binding anions, giving rise to an irregular [KO6] coordination polyhedron. The coordination mode of the cation leads to the formation of K/O layers parallel to (100). These layers are linked by the nearly coplanar anions (r.m.s. deviation of 0.064 Å of the carboxyl, aryl and O-CH2 groups from the least-squares plane) into a three-dimentional network.

The title compound, [ZnCl2(C21H15N3)], was obtained from the reaction of ZnCl2·4H2O with 4'-phenyl­terpyridine (L) and disodium 2,6-dipicolinate. The Zn2+ cation is ligated by the N atoms of the tridentate L ligand and two chloride anions, forming a ZnN3Cl2 polyhedron with a distorted trigonal-bipyramidal coordination geometry. In the crystal, nonclassical C-H...Cl hydrogen bonds are observed.

In the title compound, C22H18N4·2H2O, the organic fragment lies across a centre of inversion in the P21/n space group. The water mol­ecules form C(2)-type hydrogen-bonded chains which are linked to the 1,4-bis­(1H-benzimidazol-1-yl­methyl)­benzene mol­ecules through O-H...N hydrogen bonds, forming sheets reinforced by [pi]-[pi] stacking inter­actions between the aromatic rings within the layers.
