摘　　要：The compound [Cu2（bpy）2（PDIAla）（H2O）2]（ClO4）2·H2O（H2PDIAla = N,N＇-（p-xylylene）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） ,β = 116.3110o,V = 2021.87（18） 3,Z = 2,Dc = 1.594 Mg/m3,Mr = 970.70,μ = 1.260 mm-1,F（000） = 996,λ（MoKα） = 0.71073 ,the final R = 0.0400 and wR = 0.1050 for all observed reflections.In the structure,the O（5）-H（52）…O（4） hydrogen bonding between aqua ligand and carbonyl oxygen of the H2PDIAla ligand along the c axis produce hydrogen-bonded helices which are assembled along the b axis through O（61）-H（61）…O（2） and N（6）-H（6N）…O（2） interactions to form 2-D layers that are further linked by π···π interactions between bpy ligands to yield a three-dimensional supramolecular network.The compound [Cu2（bpy）2（PDIAla）（H2O）2]（ClO4）2·H2O（H2PDIAla = N,N＇-（p-xylylene）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） ,β = 116.3110o,V = 2021.87（18） 3,Z = 2,Dc = 1.594 Mg/m3,Mr = 970.70,μ = 1.260 mm-1,F（000） = 996,λ（MoKα） = 0.71073 ,the final R = 0.0400 and wR = 0.1050 for all observed reflections.In the structure,the O（5）-H（52）…O（4） hydrogen bonding between aqua ligand and carbonyl oxygen of the H2PDIAla ligand along the c axis produce hydrogen-bonded helices which are assembled along the b axis through O（61）-H（61）…O（2） and N（6）-H（6N）…O（2） interactions to form 2-D layers that are further linked by π···π interactions between bpy ligands to yield a three-dimensional supramolecular network.
