Abstract

The title complex, [Cu(4)(C(14)H(15)ClN(3)O(4))(2)(ClO(4))(2)(C(6)H(16)N(2))(2)], is a tetra-nuclear copper(II) complex lying about an inversion center wherein a cis-oxamide group is coordinated to both Cu atoms with bite angles of 84.45 (6) and 84.08 (10)°. Both Cu atoms adopt distorted square-pyramidal coordination geometries. The apical position of one Cu atom is occupied by an O atom from a perchlorate group, with a Cu-O bond length of 2.519 (7) Å, while the apical site of the other Cu atom is occupied by a carboxyl-ate O atom with a Cu-O distance of 2.281 (3) Å. The Cu atoms bridged by oxamide and carboxyl-ate-group bridges are separated by 5.204 (6) and 5.603 (2) Å, respectively. The crystal structure is consolidated by weak inter-molecular C-H⋯O inter-actions. Two perchlorate O atoms are disordered with unequal site-occupancy factors.

摘要

标题配合物[Cu(4)(C(14)H(15)ClN(3)O(4))(2)(ClO(4))(2)(C(6)H(16)N(2))(2)]是一个四核铜（II）配合物，位于一个反演中心周围，其中一个顺式草酰胺基团以84.45 (6)°和84.08 (10)°的咬角与两个铜原子配位。两个铜原子均采用扭曲的四方锥配位几何构型。一个铜原子的顶端位置被来自高氯酸根的一个氧原子占据，铜 - 氧键长为2.519 (7) Å，而另一个铜原子的顶端位置被一个羧酸根氧原子占据，铜 - 氧距离为2.281 (3) Å。由草酰胺和羧酸根基团桥连接的铜原子分别相距5.204 (6) Å和5.603 (2) Å。晶体结构通过弱的分子间C - H⋯O相互作用得以巩固。两个高氯酸根氧原子无序，占据因子不相等。
