Abstract

By reaction of Me 3 SiSBu with anhydrous tin(II) chloride bis(butylthio)tin was obtained that exemplified a coordination polymer [Sn(SBu) 2 ] n , whose elementary unit contained according to X-ray diffraction study three independent four-membered rings Sn 2 S 2 of unusual geometry. It was demonstrated that polymeric thiolates [E(SBu) 2 ] n , (E = Ge, Sn) readily reacted with TsiLi (Tsi = C(SiMe 3 ) 3 ) in a mixed solvent ether THF affording in a good yield ate-complexes [(Me 3 Si) 3 CE(μ-SBu) 2 Li(THF) 2 ]. Both complexes contain a four-membered ring in a butterfly conformation where the lithium atom is symmetrically bonded to both sulfur atoms, and the coordination polyhedra of Ge and Sn atoms may be regarded as distorted tetrahedra AB 3 X, where one of coordination places is occupied by unshared electron pair. The structure of the ate-complexes observed in a crystal is conserved also in solution of nonpolar solvents.
