The first octanuclear tin(IV)–oxosulfide complex
(NH4)2(Et4N)4[Sn8S12O4(SPh)6] has been synthesized by mixing stoichiometric amount of
Sn(SPh)4 and
(NH4)2WOS3 and thiophenol in DMF. The compound was crystallized in orthorhombic space group Cmcm,
Z=4,a=18.0463(4)A,b=15.7599(2)A,c=19.1914(5)A, a single crystal X-ray diffraction analysis revealed two coordinate modes of the tin atoms: five-coordinated distorted rectangular pyramid
SnOS4 and six-coordinated octahedron
SnO3S3.
