The compound [Cu2(bpy)2(PDIAla)(H2O)2](ClO4)2·H2O (H2PDIAla = N,N'-(pxylylene)dialanine, bipy = 2,2'-bipyridine) 1 has been synthesized and structurally determined by single-crystal X-ray diffraction, elemental analyses and IR spectroscopy. The crystal belongs to the monoclinic system, space group P21 with a = 10.9772(6), b = 18.5464(9), c = 11.0790(6)(A), β =116.3110°, V= 2021.87(18)(A)3, Z = 2, Dc= 1.594 Mg/m3, Mr = 970.70,μ = 1.260 mm-1, F(000) =996, λ(MoKα) = 0.71073 A, the final R = 0.0400 and wR = 0.1050 for all observed reflections. In the H2PDIA1a ligand along the c axis produce hydrogen-bonded helices which are assembled along the network.
