Synthesis,Crystal Structure and Nonlinear Optical Properties of an Oxomolybdate-copper Cluster [Cu_4(PPh_3)_6][Mo_8O_(26)]

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 article, an oxomolybdate-copper cluster, [Cu4（PPh3）6][Mo8O26] （1）, has been synthesized and characterized by single-crystal X-ray diffraction structure analysis, IR spectrum and XRD analysis. The crystal structure shows that the centrosymmetric [Mo8O26]^4- anion is built with eight MoO6 edge-shared octahedra, which belongs to the typical β-octamolybdate arrangement. The title cluster exhibits nonlinear optical properties （NLO） with effective third-order NLO absorptive index α2 refractive index n： value 12.9×10^-11 MKS and 3.13×10^-11 and esu, respectively.
