Reactions of Co(OAc)2 · 4H2 O, N, N'-dicarboxymethylbenzimidazole and 4,4'-bipy (molar ratio= 1 : 1 : 1) in H2O/DMF (volume ratio=6 : 1) at 140 ℃ afforded the title compound [Co2 (HCO2)3 (4,4'-bipy)]oo. It has been characterized by IR spectrum and its crystal structure has been determined. It crystallizes in the tetragonal symmetry with space group P43212 and lattice parameters.. a=b=0.8014(3) nm, c=1.7556(7) nm, V= 1.1282(7) nm^3, Z=4, Dc=1.797 g/cm^3, F(000)=620.0, μ=1. 533mm-1, RI= 0. 0194, and wR2 =0.0523. In this compound, Co is coordinated by two N atoms from two 4,4'-bipy and four O atoms from four formates. The 1D chain formed by Co and 4,4'-bipy was bridged by formates into 3D network.
