A new heterometallic complex {[Cu(pic)2(H2O)2][Cd2(Hdipic)2(H2O)2Cl2]}n (Mr = 1007.73) has been synthesized under hydrothermal condition and characterized by single-crystal X-ray diffraction. It crystallizes in triclinic, space group P1 with a = 5.8397(4), b = 9.8664(7), c = 14.1739(10) , α = 82.0150(10), β = 80.4540(10), γ = 82.3570(10)o, Z = 1, V = 792.47(10) 3, Dc = 2.112 g/cm3, μ(MoKα) = 2.247 mm-1, F(000) = 495, the final R = 0.0232 and wR = 0.0644 for 2748 observed reflections (I > 2σ(I)). In the complex, seven-coordinated Cd ions form a zigzag chain based on the alternated dinuclear Cd units. The neutral [Cu(pic)2(H2O)2] units are located at the centers of the inter space and fasten to the 1-D chain by hydrogen bonds.
