Abstract: | The mononuclear palladium(II) complex trans-[PdCl2(PhPPy2)2] (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. Complex 2 crystallizes in space group P21/c with a?=?12.947(1), b?=?9.142(1), c?=?33.454(2)?Å, 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. |
