Abstract

Abstract Image

The high-yield product of the reaction of [RuCl2(dmso)4] (dmso = dimethylsulfoxide) with Na[HB(mt)3] (mt = methimazolyl) is not, as reported, the complex [RuCl(dmso)2{κ3-S,S′,S′′-HB(mt)3}] but rather the isomeric [RuCl(dmso)2{κ3-H,S,S′-HB(mt)3}], which features a three-center, two-electron B−H−Ru interaction, as also found for the complex [RuH(PPh3)2{κ3-H,S,S′-H2B(mt)2}], which results from [RuHCl(PPh3)3] and Na[H2B(mt)2].
