A simple method for the preparation of octanuclear tin (IV) oxosulfide cluster and the conversion of it to decanuclear cluster

An octanuclear tin (IV) complex [(n-C4H9)4N]4 [Sn8(μ4-O)2(μ2-OH)2S12Cl6] 1 was synthesized simply by the reaction of Na2S·7H2O and SnCl4·5H2O in DMF. The yield is high and this may provide a new strategy for the preparation of other octanuclear tin (IV) oxosulfide cluster. When 1 was heated under hydrothermal conditions, a decanuclear cluster [(n-C4H9)4N]4 [Sn10(μ4-O)4(μ3-S)4(μ2-S)12Cl4]·(4,4′-bipy) 2 may be obtained. The two clusters were all characterized by X-ray structure analysis.
