One novel 1-D copper(Ⅱ)-organic compound,namely {[Cu2(PP)2(CBPC)]2·7H2O}n(1,H2CBPC=1-[(2’-carboxybiphenyl-4-yl)methyl]-2-propylimidazole-4-carboxylic acid,HPP=3-(2-pyridyl)pyrazole),was synthesized under hydrothermal conditions.X-ray diffraction analyses reveal that the two Cu(Ⅱ) ions in the distorted dimer [Cu2(PP)2] of 1 are linked by the carboxylate oxygen atoms on the phenyl and imidazole rings,respectively,forming one interesting snake-like chain.Single-crystal X-ray analyses reveal that it crystallizes in monoclinic,space group C2/c with a=30.656(8),b=12.715(3),c=22.405(5),β=122.758(3)°,V=7344(3)3,Z=4,Mr=1681.65,Dc=1.521 g/cm3,F(000)=3464,μ=1.221 mm-1,the final R=0.0453 and wR=0.1023 for 4617 observed reflections with Ⅰ> 2σ(Ⅰ).
One novel 1-D copper (II) -organic compound, namely {[Cu2 (PP) 2 (CBPC)] 2.7H2O} n (1, H2CBPC = -2-propylimidazole-4-carboxylic acid, HPP = 3- (2-pyridyl) pyrazole, was synthesized under hydrothermal conditions. X-ray diffraction analysis of the two Cu (II) ions in the distorted dimer [Cu2 ) 2] of 1 are linked by the carboxylate oxygen atoms on the phenyl and imidazole rings, respectively, forming one interesting snake-like chain. Single-crystal X-ray analysis reveals that it crystallizes in monoclinic space group C2 / c with a = 30.656 (8) b = 12.715 (3) c = 22.405 (5) β β = 122.758 (3) ° V = 7344 3 Z = 4 Mr = 1681.65 Dc = 1.521 g / cm3, F (000) = 3464, μ = 1.221 mm-1, the final R = 0.0453 and wR = 0.1023 for 4617 observed reflections with I> 2σ (I).
