In the title compound, [MnCl2(C12H8N2)2], the MnII complex displays a distorted octahedral coordination geometry formed by two phenanthroline ligands and two Cl− anions. The crystal structure is different from that reported previously for the same compound [McCann, McCann, Casey, Jackman, Devereux & McKee (1998). Inorg. Chim. Acta, 279, 24–29].

The title compound, [NiII(H2O)6][NiII(C4H4O4S)2]·4H2O, consists of [NiII(H2O)6]2+ complex dications, [NiII(C4H4O4S)2]2− complex dianions and non-coordinated water molecules. In the complex dianion, two thiodiacetate dianions coordinate to the NiII ion in a fac-SO2-tridentate chelating mode, resulting in a distorted octahedral trans-NiO4S2 coordination geometry. The crystal structure is stabilized by an extensive O—HO hydrogen-bonding network.

The title complex, [Ni(C4H4O4S)(C3H4N2)3]·H2O, displays a distorted octahedral NiN3O2S coordination geometry, formed by three imidazole (imid) ligands and one thiodiacetate dianion. The NiII atom is displaced from one of the imid planes, and the angle between the corresponding Ni—N bond and the imid plane is 21.94 (19)°. This spatial orientation is stabilized by an intermolecular C—Hπ interaction between one imid ligand and the C—H bond of an adjacent imid ligand.

In the title complex, [Cd(C4H4O4S)(C7H6N2)3]·2H2O, the CdII atom is surrounded by three benzimidazole ligands and one thiodiacetate dianion to complete a distorted octahedral CdN3O2S coordination geometry. The tridentate TDA chelates to the CdII atom in a facial mode. A C—Hπ interaction and hydrogen bonding between neighboring complexes help to stabilize the crystal structure.
metal-organic compounds
In the title compound, [Co(C8H4O4)(C7H6N2)2]n, the terephthalate dianions bridge CoII ions through terminal carboxyl groups to form polymeric complex chains; one carboxyl group coordinates in a monodentate manner and the other chelates to the Co atom. Two benzimidazole ligands also coordinate to the Co atom to complete a distorted trigonal–bipyramidal coordination geometry. The crystal packing is stabilized by N—HO hydrogen bonds and π–π stacking involving the benzimidazole ligands, with a face-to-face separation of 3.454 (11) Å.

In the title compound, [Co(C7H5O3)2(C7H6N2)2]·0.25H2O, the CoII atom is coordinated by two 4-hydroxybenzoate (hbz) anions and two benzimidazole (bzim) ligands in a distorted trigonal–bipyramidal geometry. The carboxylate group of one of the hbz anions chelates to the Co atom with a normal Co—O bond [1.993 (2) Å] and a longer Co—O bond [2.561 (3) Å]. Aromatic π–π stacking is observed between neighbouring bzim ligands but not between hbz ligands.
metal-organic compounds
In the title complex, [Cd(C4H4O4S)(C3H4N2)(H2O)]n, the CdII atom is surrounded by one imidazole ligand, one water molecule and two thiodiacetate dianions in a distorted octahedral CdNO4S coordination. Each thiodiacetate dianion coordinates to two independent Cd atoms, one as a tridentate chelate, the other in a monodentate fashion through a carboxylate O atom. The thiodiacetate dianions bridge neighbouring CdII atoms, forming zigzag polymeric chains.
organic compounds
In the title compound, C7H7N2+·C8H4NO6−, the partially overlapped arrangement and the shorter face-to-face distance of 3.457 (4) Å indicate π–π stacking between parallel benzimidazolium cations, whereas the longer face-to-face distance of 3.649 (6) Å suggests normal van der Waals contacts between parallel benzene rings of neighbouring nitroterephthalate anions.
