The new cadmium (Ⅱ) complex [Cd(tbz)Cl2]·EtOH(1)(tbz = 1,3 -bis (benzimidazol-2-yl) propane)was synthesized and characterized by single-crystal X-ray diffraction. The crystal is of monoclinic, space group P21/cwitha = 0.96080(10), b = 1.30150(14),c = 1.62084(17) nm,β= 90.109(2)°, V = 2.0268(4)nm3, Z = 4, Mr= 503.70, Dc= 1.651 g/cm3, F(000) = 1 008,μ = 1.357 mm-1, thefinalR = 0.025 1and wR = 0. 064 8 for 3 549 observed reflections (Ⅰ＞2r(Ⅰ) ). The coordination geometry of cadmium atom is distorted tetrahedral, coordinated by two nitrogen atoms from one tbz ligand, and two Cl- cations..
