A novel binuclear cupric complex with Gly GlyO chelate ring and 4,4′ dipyridyl as an intermediate radical was synthesized by the reaction of 4,4′ dipy ridyl and cupric nitrate in aqueous solution. The structural formula of the complex was confirmed as [(H 2NCH 2CONHCH 2COO)(C 10 H 8N 2)Cu(OH)(H 2NCH 2CONHCH 2COO)]·10H 2O by X ray single crystal structure analysis. Crystallographic data are as follows: a triclinic system with a space group P 1, a =0 712 4(2) nm, b =1 140 5(1) nm, c =1 143 4(1) nm, α=67 65°, β=79 02° , γ=77 97° , V =0 834(3) nm 3, Z =1. The structural data were refined by the block matrix least squares program to final R value of 0 072 7.
