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。
This paper reports a new copper (III) phosphonate compound: Cu (O3PC6H4COOH) (1). The compound has a novel layered structure in which two core units formed by the {CuO4} side of a twisted planar structure are connected by a {CPO3} tetrahedron to form an inorganic layer containing 4-, 8-, and 14-membered rings. Benzoic acid groups are joined by medium-strength hydrogen bonds and filled between layers. Magnetic characterization shows the presence of antiferromagnetic interactions between the copper ions. The crystal of compound 1 belongs to the monoclinic system, C2 / c space group.
