1-phenyl-tetrazole-5-thione (dpimdztH) afforded mononuclear mixed-ligand complexes with the general formula [CuX(PPh 3 ) 2 (thione)], in which the thione acts in a terminal bonding mode. All copper(I) complexes are found to be photoluminescent in the solid state at ambient temperature, with their emission maxima influenced by the type of heterocyclic thione, as well as (to a smaller extent) the halide present in each
摘要四聚体簇[CuX(PPh 3)] 4(X = Br或Cl)与一系列小尺寸,五元环N-杂环硫酮,5-甲基-1,3,4-噻二唑-2的反应-硫酮(mtdztH),5-氨基-1,3,4-噻二唑-3-硫酮(atdztH)和4,5-二苯基-咪唑-2-硫酮(dpimdztH),摩尔比为1:4,在乙腈/甲醇混合物,导致分离出对称的,一般类型[CuX(PPh 3)(μ-S-硫酮)] 2的混合配位膦/硫酮-S桥联双铜物质,铜中心呈扭曲的四面体由PS 2 X施主集组成的协调环境。相比之下,与碱性较低且空间要求更高的1-苯基-四唑-5-硫酮(dpimdztH)进行的类似反应可得到具有通式[CuX(PPh 3)2(硫酮)]的单核混合配体配合物,其中硫酮以末端键合模式起作用。发现所有铜(I)配合物在环境温度下均处于固态光致发光,其发射最大值受杂环硫酮类型以及每种情况下存在的卤化物(在较小程度上)的影响。
