In the title complex, [Cu(C8H7O2)2(C3H4N2)2], the CuII atom, located on an inversion center, has a square-planar coordination geometry formed by imidazole molecules and 3-methylbenzoate anions. Hydrogen-bonding and C—H
π interactions occur between imidazole and methylbenzoate ligands of neighboring complex molecules.

In the title polymeric compound, [Mn(C4H4O4)(C7H6N2)2(H2O)]n, the MnII atom is located on an inversion center and is coordinated by succinate dianions and benzimidazole and water molecules with an elongated octahedral coordination geometry. The long Mn—O(water) bond distance of 2.4982 (3) Å shows the rather weak nature of this bond. The succinate dianion and water molecule are located on an inversion center and a twofold axis, respectively; they bridge the MnII atoms to form a polymeric structure.

In the crystal structure of the title compound, [CuCl(C12H8N2)2]NO3·C7H5NO4.H2O, the CuII ion assumes a trigonal–bipyramidal CuN4Cl coordination geometry arising from two bidentate 1,10-phenanthroline (phen) ligands and one chloride ion, with the chloride ion in an equatorial position. A partially overlapped arrangement between parallel phen rings of neighboring complexes, with face-to-face distances of 3.529 (9) and 3.452 (8) Å, suggests the existence of π–π stacking.

In the title compound, [Co(C4H4O5)(C7H5N3O2)(H2O)2]·H2O, the CoII atom is coordinated by one tridentate oxydiacetate dianion, one monodentate nitrobenzimidazole molecule and two water molecules in a distorted octahedral geometry. The face-to-face distance of 3.345 (14) Å between parallel nitrobenzimidazole ligands of neighboring complexes indicates the existence of π–π stacking.

In the title polymeric complex, [HgI2(C7H6N2)]n, the HgII atom is coordinated by one benzimidazole (bzim) and three I− anions with a distorted tetrahedral geometry; one I− anion is in a monodentate coordination mode and the other two are bridging. The two bridging Hg—I bond distances differ significantly [2.7420 (7) and 3.0543 (7) Å]. The face-to-face separation of 3.31 (3) Å between the mean planes of parallel bzim ligands and the partially overlapped arrangement indicate the existence of π–π stacking.
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.
