An Eicosanuclear Heterothiometallic Mo/S/Cu Cluster: Synthesis and Third-Order Nonlinear Optical Property
A potassium-crownether host–guest cation-templated synthetic method was used to build a heterothiometallic Mo/S/Cu cluster {[(K ⊂ dibenzo-18-crown-6)(NMP) 2 ] 2 [(K ⊂ dibenzo-18-crown-6)(NMP)] 2 [Mo 8 S 32 Cu 12 ]·H 2 O} ( 1 ). 1 was structurally determined by X-ray single crystal and powder diffrac...

exhibits a unique octameric eicosanuclear supra-cubane-like architecture. Potassium-crownether cations show “satellite-receiver”-shaped and hexagonal-pyramidal configurations. Moreover, the third-order nonlinear optical (NLO) property was studied through Z-scan method (532 nm, 4 ns pulses), which reveals that
