Monovalent indium in a sulfur-rich coordination environment: synthesis, structure and reactivity of tris(2-mercapto-1-tert-butylimidazolyl)hydroborato indium, [TmBut]In

Abstract

[Tm^But]In, the first structurally-characterized monovalent indium compound that features a sulfur-rich coordination environment, has been synthesized via treatment of InCl with [Tm^But]K; in contrast to the thallium counterpart, the lone pair of [Tm^But]In is a site of reactivity, thereby allowing formation of [Tm^But]In→B(C₆F₅)₃ and [Tm^But]In(κ²-S₄) upon treatment with B(C₆F₅)₃ and S₈, respectively.
