networking of 15-membered O2S2-macrocycle isomers (L1 and L2) induced by interdonor distances is reported. In copper(I) bromide complexation, the isomer L1 incorporating a shorter sulfur-to-sulfur separation yielded a discrete dimer complex [(μ-Cu2Br2)(L1)2] (1) in which two macrocycles are bridged by a Cu2Br2 square cluster. While, the reaction of copper(I) bromide with the isomer L2 incorporating a longer
摘要 对供体间距离诱导的 15 元 O2S2-大环异构体(L1 和 L2)的外配位网络进行了比较研究。在溴化铜 (I) 络合中,异构体 L1 结合了较短的硫磺分离,产生了离散的二聚体络合物 [(μ-Cu2Br2)(L1)2] (1) 其中两个大环由 Cu2Br2 方形簇桥接. 同时,溴化铜 (I) 与异构体 L2 的反应结合了更长的硫磺分离,得到了双链一维 (1D) 配位聚合物 [(μ4-Cu2Br2)(L2)2]·CH2Cl2 }n (2) 作为动力学产物,其转化为 [(μ4-Cu2Br2)(L2)2]n (3) 作为热力学产物,具有不同的一维连接模式。
