摘要

The reaction of 2,2'-bipyridine-5,5'-dicarboxylic acid (HO2CC12H6N2CO2H, H-2 bpydicarb) with the appropriate metal salt in water provided the mononuclear complexes [M(II)(bpydicarb)(H2O)(4)]center dot 2H(2)O where M(II)= Co and Ni. The isomorphous materials exhibit neutral six-coordinate metal-ligand complexes with MN(2)O4 geometry. Charge balance is achieved through deprotonation of the carboxylate groups. The Co compound crystallizes in the monoclinic space group C2/c with a = 12.696(4) angstrom, b = 9.195(4) angstrom, c = 13.207(5) angstrom, beta = 93.78(1)degrees; the isomorphous Ni compound exhibits cell parameters a =12.477(4) angstrom, b =9.818(3) angstrom, c =12.658(4) angstrom, beta =92.099(6)degrees.
