Two hexanuclear cobalt clusters [Co6(bms)12]·(X)6·yH2O (1, X=NO3 , y = 12; 2, X= ClO4- , y=8) and one new trinuclear nickel cluster [Ni3S(bms)3]·NO3·C2H5OH (3) (Hbms = (1H-benzoimidazol-2-yl)-methanethiol) have been synthesized and characterized by elemental analysis, IR spectrum, and X-ray single-crystal diffraction. Compound 1 crystallizes in the trigonal system, R3 space group, and consists of hexanuclear CoIII units, which are bridged by μ2-S-benzimidazoles in a square arrangement around cobalt. Compound 2 crystallizes in the monoclinic system, P21/n space group, and also consists of hexanuclear CoIII units containing the same kind of μ2-S benzimidazole bridges like 1, but contains different counter anions and lattice waters. Compound 3 crystallizes in the orthorhombic system, Pbca space group, and is composed of trinuclear NiII units. These results show that geometries and sizes of the corresponding anions as well as their coordinating mode and hydrogen-bonding properties are important in determining the final structures of the assemblies.
