The flexibility of binding modes of the supersilyl thiolate ligand SSitBu3−

The synthesis and structural characterization of [Zn(SSitBu3)2]2 are described. The degradation of sulfur with [Zn(SitBu3)2] in tetrahydrofuran yielded the supersilyl thiolate complex [Zn(SSitBu3)2]2. X-ray quality crystals of [Zn(SSitBu3)2]2 were grown from a benzene solution at ambient temperature (monoclinic, C2/c). The trigonal-planar coordinate zinc atoms in [Zn(SSitBu3)2]2 are surrounded by one terminal and two bridging thiolate ligands. The bonds between the Zn and S atoms of the terminal ligands are significantly shorter than those between the Zn and S atoms of the bridging ligands.
