Synthesis,Structural Characterization and Spectroscopic Properties of a Copper(Ⅰ)Complex Containing Tri-phosphine Ligand with C-H…π and π…π Interactions

设计合成了一个铜(I)的配合物[Cu(Triphos)(PPh3)](BF4)(1),通过红外、核磁氢谱和磷谱、紫外光谱、X-射线单晶衍射等对其进行结构表征。晶体结构研究表明,该晶体属于单斜晶系,P2(1)/c空间群;晶胞参数为a=12.8072(4),b=14.3693(4),c=25.8438(8),V=4756.0(2)3,Z=4。配合物1中的铜(I)原子同时与单齿配体PPh3和三齿配体Triphos的P原子配位,形成一个扭曲的四面体构型。配合物通过C-H…π、π…π堆积作用力形成三维网状结构。在室温下,配合物1的乙腈溶液在265 nm有紫外吸收峰,在399 nm有荧光发射峰。CCDC:1017906。

A titled complex, [ Cu（Triphos） （ PPh3 ） ] （ BF4 ） （ 1）, （ Triphos = N,N, N-tris （ diphenylphosphinomethyl） amine） , was designed and synthesized. The complex was characterized by IR, ^1H NMR, ^31p NMR, UV-Vis spectrum and X-ray crystal structure analysis. The structural analysis showed each copper （I） is four-coordinated by four P atoms and adopts a distorted-tetrahedral geometry, and the packing structure is controlled by π…π and C-H...π interactions. The maximum absorption at 265 nm and emission centered at 399 nm in acetonitrile solution were also observed for complex 1. The unit cell parameters for complex 1 are as follows, a = 12. 8072（4） A, b = 14, 3693（4） A, c=25.8438（8） A, V=4756.0（2） A3, Z=4.
