Abstract

Treatment of [Et₄N]₂[WSe₄] with a 1:1 mixture of AgNO₃ and PCy₃ (Cy = cyclohexyl) in the absence of iodide afforded a linear trinuclear compound [(μ-WSe₄) (AgPCy₃)₂] (1). A similar reaction in the presence of iodide gave rise to the isolation of the cubanelike compound [(μ₃-WSe₄)Ag₃(PCy₃) ₃(μ₃-I)] (2). Treatment of [Et₄N] ₂[WSe4] with AgI in the presence of bidentate phosphine ligands bis(diphenylphosphino)amine (dppa) and bis(diphenylphosphino)-methane (dppm) afforded the tetranuclear compounds [(μ₃-WSe₄)Ag ₃(μ-I)(μ-dppa)₂] (3) and [(μ₃-WSe ₄)Ag₃(μ₃-I)-(μ-dppm)₂] (4), respectively, which exhibit an open butterfly configuration. A novel hexanuclear cluster compound [(μ₃-WSe₄)₂Ag ₄(μ-dppm)₃] (5) was obtained from interaction of [Et₄N]₂[WSe₄] with AgNO₃ and dppm in the absence of iodide source. The above cluster compounds are electrically neutral and air-stable in both solution and the solid state and have been characterized by electronic, infrared, mass, and NMR spectroscopies. The solid-state structures of five cluster compounds have been established by X-ray crystallography. The nonlinear optical properties of compounds 4 and 5 were examined by z-scan techniques with 7 ns pulses at 532 nm. The optical limiting effects of compounds 1, 2, 4, and 5 were determined and compared with related argentoselenometallic compounds.
