| 中文摘要: |
| 设计合成了一个铜(I)的配合物 [Cu(Triphos)(PPh3)](BF4) (1), 并对其进行了红外、氢谱、磷谱、紫外光谱等相关表征,并利用X-射线单晶衍射仪测定了配合物的结构。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堆积作用力形成维网状结构。在室温下,配合物1的乙腈溶液中观察到,在265 nm有紫外吸收峰；在399 nm有荧光发射峰。CCDC: 1017906, 1 |
| 英文摘要: |
| A title complex, [Cu(Triphos)(PPh3)](BF4) (1), (Triphos= N, N, N-tris(diphenylphosphino-methyl)amine), was designed and synthesized. The complex was characterized by IR, 1H-NMR, 31P–NMR, UV-Vis spectrum and X-ray crystal structure analysis (CIF file CCDC no. 1017906). The structural analysis shows each copper (I) is four coordinate P4 and adopts a distorted-tetrahedral geometry, and the packing structure is controlled by π...π and C–H...π interactions. The absorption spectra at 265 nm and emission centered at 399 nm in acetonitrile solution were also observed for 1. The unit cell parameters for 1: a =12.8072(4), b = 14.3693(4), c = 25.8438(8) ?, V = 4756.0(2) ?3, Z = 4. |
