Synthesis and structural characterization of [TpBut2]GaS: a terminal gallium sulfido complex in a system for which the indium counterpart is a tetrasulfido derivative, [TpBut2]In(η2-S4)

Abstract

The synthesis of the terminal gallium sulfido complex [Tp^But₂]GaS via the reaction of monovalent [Tp^But₂]Ga with elemental sulfur provides a striking contrast with the formation of the tetrasulfido derivative [Tp^But₂]In(η²-S₄) in the indium system; such an observation provides a strong indication that gallium exhibits a greater tendency to partake in multiple bonding than does indium.
