New skeletal 3D polymeric inorganic cluster [W4S16Cu16Cl16]n with Cu in mixed-valence states: solid-state synthesis, crystal structure, and third-order nonlinear optical properties.
A new 3D polymeric inorganic cluster with Cu in mixed-valence states was synthesized by the solid-state reaction of (NH4)2WS4, S8, CuCl, and Et4NCl; S8 may be regarded as the oxidizing agent converting Cu(I) to Cu(II) and causing the polymerization of [WS4]2-. The third-order nonlinear optical (NLO) properties are determined, and the results show that the cluster exhibits both large NLO absorptive and strong refractive behaviors.
