A new cobalt complex Co(C10H8N2)(H 2O)3[C9H11O2(COO)] with methy-5-norbornene-2,3-dicarboxylic anhydride acid (MNA) and 2,2'-bipyridine as ligands has been synthesized in the mixed solvents of ethanol and water. It crystallizes in monoclinic, space group P21/c with a = 13.0430(13), b = 21.014(2), c = 7.5151(7) Å, β = 102.319(2)°, V = 2012.4(3) Å3, Dc = 1.529 g/cm3, Z = 4, F(000) = 964, GOOF = 1.051, the final R = 0.0457 and wR = 0.0974. The crystal structure shows that the cobalt ion is coordinated with four oxygen atoms from one MNA molecu...
