Abstract: The title compound was synthesized by the reaction of cis-[Co(phen)2Cl2]Cl·3H2O with DL-alanine at pH = 8, and isolated using a column chromatographic method. Its crystal structure was determined. The crystal structure belongs to mono-clinic system, space group P21/c, with a = 0. 9549(6) nm, b=2.3746(8) nm, c= 1.0782(4) nm, β=114.13(3)°, Z = 4, Dc= 1. 50 g/cm3. The final refinement converged to R = 0. 047 for 3246 independent observed reflections. In the octahedral coordination sphere formed by the cobalt atom and the coordinate atoms, N, O of DL-alan-inato ligands are in the configuration of trans-N,N form.
