层状有机膦酸铜配合物Cu(O3PC6H4COOH)

摘要

A new copper phosphonate complex Cu(O3PC6H4COOH)(1) is reported in this paper. It shows a novel type of layered structure, where dimers of distorted {CuO4} planes are connected by {CPO3} tetrahedra, forming an inorganic layer containing 4-, 8- and 14-member rings. The phenylcarboxylate groups fill in the interlayer spaces with moderate strong hydrogen bond interactions. Magnetic analysis shows antiferromagnetic interaction between Cu(Ⅱ) ions. Crystallographic data for 1: monoclinic, space group C2/c, a=3.813 5(7) nm, b=0.811 85(14) nm, c=0.52249(9) nm,β=92.816(4)°, V=1.615 7(5) nm3, Z=8. CCDC: 703675.%本文报道了一个新的有机膦酸铜化合物:Cu(O3PC6H4COOH)(1).该化合物具有新型层状结构,由扭曲平面结构的{CuO4}共边形成的二核单元通过{CPO3}四面体连接起来,形成一个含有4-,8-,和14-元环的无机层.苯甲酸基团通过中等强度的氢键连接起来.并填充在层与层之间.磁性表征显示铜离子之间存在反铁磁性相互作用.化合物1的晶体属单斜晶系,C2/c空间群.
