Monovalent indium in a sulfur-rich coordination environment: synthesis, structure and reactivity of tris(2-mercapto-1-tert-butylimidazolyl)hydroborato indium, [TmBut]In†
Abstract
[TmBut]In, the first structurally-characterized monovalent indium compound that features a sulfur-rich coordination environment, has been synthesized via treatment of InCl with [TmBut]K; in contrast to the thallium counterpart, the lone pair of [TmBut]In is a site of reactivity, thereby allowing formation of [TmBut]In→B(C6F5)3 and [TmBut]In(κ2-S4) upon treatment with B(C6F5)3 and S8, respectively.
