Abstract
Reaction of (NH4)2[WS4], [Ag(MeCN)4](PF6) and dppm (molar ratio = 1∶2∶4) in the solid state at 110 °C followed by extraction with CH2Cl2 yielded a hexanuclear neutral cluster [(WS4)2Ag4(dppm)3] 1, while the same materials when mixed directly in CH2Cl2 produced a tetranuclear cluster salt [WS4Ag3(dppm)4](PF6) 2; both compounds showed modest third-order optical nonlinearities.
