摘要 反式单核钯(Ⅱ)配合物[-Pd(PhPPy2)2Cl2](1)与ECu(CH3CN)4]ClO4反应得到异双核配合物[(PhPPy2)2PdCuCl2]ClO4·2CH3CN(2),其中金属离子由两个PhPPy2配体以一种新的模式所桥联。配合物2属于P21/c空间群,晶胞参数a、b、c分别为1.294 7(1)nm,0.914 2(1) nm和3.345 4(2)nm,β为99.698(1)°。2中的Pd(Ⅱ)和Cu(Ⅰ)离子分别为扭曲的四面体和平面正方构型。室温下,该配合物的溶液发光。 The mononuclear palladium (Ⅱ) complex trans-[Pd (PhPPy2 )2Cl2] (1) reacts with [Cu (CH3CN)4]ClO4 to afford the heterobinuclear [(PhPPy2 )2PdCuCl2]ClO4·2CH3CN (2), bridged by two PhPPy2 ligands in a new mode. The complex 2 crystallizes in space group P21/c with a = 1. 294 7 (1), b = 0. 914 2(1), c = 33. 454 4(2) nm,β=99. 698(1)°. The copper(Ⅰ) and palladium(Ⅱ) ions in 2 adopt distorted tetrahedral and square planar geometry, respectively. At room temperature, the complex is photoluminescent in solution.
