| 摘要: 本文用(NH4)2WS4，Ag[S2P(OCH2Ph)2]和PPh3为原料合成了簇合物[WS4Ag3(PPh3)3{S2P(OCH2Ph)3}]，并得到了晶体。晶体属正交晶系，空间群为P212121，晶胞参数a=1.32370(4)nm，b=1.34427(4)nm，c=3.83246(11)nm。X-射线单晶结构测定结果表明它具有巢状分子结构，配体(PhCH2O)2PS2-(简称dtp)的两个S原子中的一个硫原子仅与一个金属原子配位，另一个硫原子则同时与两个金属原子配位。簇合物的非线性光学性质用脉宽8ns激光在532nm波长进行了研究。该化合物表现为一定的光学吸收和强的自聚焦效应，其三阶非线性吸收系数α2=1.50×10-10m·W-1，折射系数n2=2.45×10-11esu。 | |

| Abstract: The cluster [WS4Ag3(PPh3)3{S2P(OCH2Ph)3}] had been synthesized from the reaction of (NH4)2WS4，Ag[S2P(OCH2Ph)2] and PPh3， and then it was characterized by IR and elemental analyses. The structure of [WS4Ag3(PPh3)3{S2P(OCH2Ph)3}] was determined by single crystal X-ray diffraction revealing that the cluster consist of a nest-shaped core. The W atom is tetrahedrally coordinated by four S atoms. The dithiophosphate ligand adopts a triply bridging role， employing two sulfur atoms to coordinate to the three Ag atoms： one sulfur atom binds to one Ag atom， the other to the rest two. The nonlinear optical properties were studied with an 8ns pulsed laser at 532nm. Its optical responses to the incident light exhibited considerably optical absorptive and strong self-focusing effect with α2=1.50×10-10m·W-1， n2=2.45×10-11esu. CCDC： 202239. | |
