以PPh3(三苯基膦)为配体合成出具有Ag(I)-Ag(I)相互作用的新型立方烷型银配合物[Ag4Br4(PPh3)4]。用物理、化学、光谱学等方法对其进行了表征,单晶衍射结果表明,该配合物为单斜晶系,C2/c空间群,晶胞参数为:a(Å)=27.151(19),b(Å)=16.246(12),c(Å)=17.990(12),α(°)=90,β(°)=109.610,γ(°)=90,Volume(Å3)=7475(9),其中每个Br原子分别与两个三齿配位的Ag原子桥联而成椅式结构。运用荧光光谱分析了PPh3配体和[Ag4Br4(PPh3)4]的固态发光性能,并探讨了配体和配合物的热稳定性和电化学性质。

A novel cubic alkyl silver complex[Ag4Br4(PPh3)4]with Ag(I)-Ag(I)interaction was synthesized using PPh3(triphenylphosphine)as a ligand.Physics,chemistry,spectroscopy and other methods were used to characterize it.The single crystal diffraction results showed that the complex was a monoclinic system,C2/c space group,and the unit cell parameter was a(Å)=27.151(19),b(Å)=16.246(12),c(Å)=17.990(12),α(°)=90,β(°)=109.610,γ(°)=90,Volume(Å3)=7475(9),in which each Br atom is bridge-type structure formed by bridging two tridentate coordination Ag atoms.The solid-state luminescence properties of PPh3 ligands and[Ag4Br4(PPh3)4]were analyzed by fluorescence spectra,and the thermal stability and electrochemical properties of the ligand and complex were discussed.
