The title compound [Cd(IM2py)2Cl2], where IM2py = 2-(2'-pyridinyl)-4,4,5,5-tetra- methylimidazoline-1-oxyl, has been prepared and structurally characterized by X-ray diffraction. It crystallizes in monoclinic, space group C2/c with a = 18.436(6), b = 9.255(3), c = 15.831(5)A,β=100.274(5)o, C24H32CdCl2N6O2, Mr = 619.86, V = 2658.0(14)A3, Z = 4, Dc = 1.549 g/cm3, μ(MoKα) = 1.056 mm-1, F(000) = 1264, the final R = 0.0324 and wR = 0.0659 for 2725 independent reflections with Rint = 0.0378. The title complex exists as discrete mononuclear molecules, adopting a distorted octahedral [cis(Cl)-trans(py)] configuration with the cadmium(II) ion being bonded to two bidentate radicals and two chlorine atoms. There exist π…π stacking interactions between the adjacent parallel pyridyl rings of the complex in the ac plane.
