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 analyzes and IR spectroscopy. The crystal belongs to the monoclinic system, space group P21 with a = 10.9772 (6), b = 18.5464 (9), c = (, Β = 116.3110o, V = 2021.87 183, Z = 2, Dc = 1.594 Mg / m3, Mr = 970.70, μ = 1.260 mm-1, 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 the 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.
