本文报道了一个多酸簇合物[Cu4(PPh3)6][Mo8O26]的合成、X-射线单晶结构分析及IR、XRD表征。单晶结构表明中心对称的[Mo8O26]4-是由8个共边的MoO6八面体组成。该化合物具有较好的三阶非线性光学性质,其三阶非线性吸收和折射系数分别为12.9×10-11MKS和3.13×10-11esu。
In this paper, the synthesis of a polyacid cluster [Cu4 (PPh3) 6] [Mo8O26], X-ray single crystal structure analysis and characterization by IR and XRD were reported. The single crystal structure shows that the centrosymmetric [Mo8O26] 4- is composed of eight co-ordinated MoO6 octahedra. The compound has good third-order nonlinear optical properties and the third-order nonlinear absorption and refraction coefficients are 12.9 × 10-11 MKS and 3.13 × 10-11 est, respectively.
