A novel peptide complex was synthesized by a solid-solid reaction of glycyl-L-glutamine monohydrate and bismuth trichloride powders. The formula of the complex is (BiCl(3))(2) [NH(2)CH(2)CONHCH(COOH)CH(2)CH(2)COOHH(2)O](3). The crystal structure of the complex belongs to monoclinic system with the lattice parameters: a = 0.6914 nm, b = 0.7378 nm, c = 1.0005 nm, beta = 194.1( degrees ). The characterization results of IR, Raman spectra and thermal analysis show that complex is dimer and unidentate coordination. Each bismuth atom and three chlorine atoms are coplanar in the complex.
