Hydrothermal reaction of 1,10-phenanthroline with CdCl2·2.5H2O in aqueous solution leads to the complex of [Cd(μ-Cl)2(phen)]n (phen = 1-10-phenanthroline). The crystal structure has been determined by X-ray analysis. It crystallizes in monoclinic with space group C2/c, a = 16.947(3), b = 10.529(2), c = 7.235(1) , β = 110.795(3)°, V = 1208.8(3) 3, Z = 4, Dc = 1.997 g.cm-3, μ= 2.22 mm-1, F(000) = 704, R = 0.0231, Rw = 0.0626 for 1194 reflections with I > 2σ (I). In the crystal structure, the [Cd(phen)]2+ units are bridged by chloride ions to form 1D chain. The 1D chains combine through π……π interactions of phen groups to form 2D infinite molecular zipper.
