Abstract

Treatment of the (isocyanoborane) gold(I) chloride adduct [LAuCl] [L = (H3C)(3)NB(H)(2)NC] with KI at room temperature yields the unusal title compound, bis[isocyano(trimethylamino) borane] gold(I) diiodoaurate(I), [Au(C4H11BN2)(2)][ AuI2], which forms via an in situ rearrangement of isocyanoborane and halide ligands. The structure consists of alternating [L2Au](+) and [AuI2](-) ions, which form an infinite linear one-dimensional chain due to aurophilic Au...Au interactions. Both Au atoms occupy inversion centres.
