069(3) A in each complex. The coordination around each copper atom of the complexes is essentially a square planar configuration with one sulfur and two alkoxo-oxygen atoms of HL1 or L2 and one oxygen atom of carboxylates. Each alkoxo-group asymmetrically bridges with the Cu1–O1 bonds (1.90—1.92 A), which are shorter than the Cu1′–O1 bonds (1.93—1.97 A). The −2J values for complexes 3,...
一系列新的双核铜 (II) 与 1,3-双(羟甲基)-2-咪唑烷硫酮,[Cu(RCOO)(HL1)]2(其中 R = CH3 (1), C6H5 (2), 2- CH3C6H4 (3)、4-CH3C6H4 (4)、2-ClC6H4 (5) 和 2-BrC6H4 (6)),并与 1-羟甲基-3-甲基-2-咪唑烷硫酮,[Cu(RCOO)(L2) ]2(其中 R = CH3 (7)、2-CH3C6H4 (8) 和 4-CH3C6H4 (9)),已制备。配合物1-9的磁化率数据符合通常的二聚体方程,-2J值范围为227至992 cm-1。3、4、7 和 9 的晶体结构分析表明,两个铜原子通过两个烷氧基桥连接,每个配合物中的间距为 3.015(3)-3.069(3) A。配合物的每个铜原子周围的配位基本上是一个方形平面构型,具有一个硫和两个 HL1 或 L2 的烷氧-氧原子以及一个羧酸盐的氧原子。每个烷氧基不对称地与比
