The title compound, [Sn(μ–S){SSi(O t Bu) 3 } 2 ] 2 ( 1 ), containing four–coordinated tin(IV), crystallizes in two polymorphic modifications. The orthorhombic 1a –form has been obtained in the reaction of ( t BuO) 3 SiSH and Et 3 N with SnCl 2 , whereas the triclinic 1b –form in the reaction with SnCl 4 as substrate. The crystal and molecular structures of both polymorphs ( 1a as a redetermination) have been determined by a single–crystal X–ray diffraction study at room temperature. The title compound was shown to react with ammonia and ammonia complexes of some d –block metal cations giving products of Sn–S bond cleavage.
