Abstract

A new thulium(III)-copper(I) heterometallic coordination polymer, Cu(4)Tm(2)Br(3)(C(6)H(4)NO(2))(6)(OH)(H(2)O)(4), has been prepared by a hydro-thermal method. The Tm and both Cu atoms lie on mirror planes. The Tm atom is seven-coordinate with a capped distorted trigonal-prismatic coordination geometry, while the Cu atoms adopt trigonal CuBrN(2) and tetra-hedral CuBr(3)N coordination modes, respectively. The Cu atom in the trigonal coordination environment is disordered over two sites of equal occupancy. The crystal structure is constructed from two distinct units of dimeric [Tm(2)(μ(2)-OH(IN)(6)(H(2)O)(4)] cores (IN = isonicotinate) and one-dimensional inorganic Cu(4)Br(3) chains, which are linked together, forming heterometallic Cu-halide-lanthanide-organic layers.

摘要

通过水热法制备了一种新型的铥(III)-铜(I)异金属配位聚合物Cu(4)Tm(2)Br(3)(C(6)H(4)NO(2))(6)(OH)(H(2)O)(4)。铥原子和两个铜原子均位于镜面上。铥原子为七配位,具有盖帽畸变三角棱柱配位几何构型,而铜原子分别采用三角CuBrN(2)和四面体CuBr(3)N配位模式。处于三角配位环境中的铜原子在两个占有率相等的位置上无序分布。晶体结构由两个不同的二聚体[Tm(2)(μ(2)-OH(IN)(6)(H(2)O)(4)]核(IN = 异烟酸酯)单元和一维无机Cu(4)Br(3)链构成,它们连接在一起形成异金属铜-卤化物-镧系-有机层。
