A new tetranuclear cluster [Co-4(bm)(6)Cl-2]center dot(H2O)(2)center dot(CH3OH) (1, Hbm is (1H-benzimidazol-2-yl)-methanol) has been synthesized by solvothermal method and structurally determined by IR, elemental analysis, and single-crystal X-ray diffraction. Complex 1 belongs to monoclinic space group P2(1)/n with a = 21.1713(5), b = 12.7948(3), c = 24.0195(9) angstrom, beta = 95.309(3)degrees, V = 6478.6(3) angstrom(3), Z = 4, F(000) = 2568, D-c = 1.289 g.cm(-3), M-r = 1257.63, mu = 9.096 mm(-1), S = 1.000, the final R = 0.0861 and wR = 0.2552 for 4956 observed reflections with I > 2 sigma(I). Two connected face-sharing cubes are observed in the framework of 1, each with one vertex missing. Complex 1 forms a 2-D network through N-H center dot center dot center dot O hydrogen bonds. The apparent holes can be observed.
