The title complex [CdLCl2] 1 (C10H15CdCl2N3, Mr = 360.55) has been synthesized by the reaction of CdCl2(2.5H2O with the tridentate Schiff base L, N,N-dimethyl-N'-pyridin-2-yl- methylene-1,2-diaminoethane, which is derived from the condensation reaction of pyridine-2- carboxaldehyde and N,N-dimethylethylenediamine. It crystallizes in the monoclinic system, space group C2/c with a = 25.054(13), b = 7.532(4), c = 16.119(8)(A°),β= 116.238(8)°, V = 2728(2)(A°)3, Z = 8, Dc = 1.756 g/cm3, μ(MoKα) = 1.970 mm-1, F(000) = 1424, R = 0.0297 and wR = 0.0625. Crystal analyses reveal that the cadmium atom is coordinated by two chlorine atoms and three N atoms from the tridentate ligand in a distorted tetragonal pyramidal environment. Each complex molecule is connected with four surrounding ones to form 2D network by hydrogen bonds along the bc plane. The chlorine atoms act as acceptors and the carbon atoms of the tridentate Schiff base as donors with the C-H…Cl distances in the range of 3.518～3.752(A°).
