Unexpected Diversity within Solid‐State Structures of Methanetrisulfonate Salts

Abstract

The structural properties of various salts of methanetrisulfonic acid (H3mts) are described, spanning the free acid, ammonium and alkali metals (Na, K, Cs), first row transition metals (Cr, Co−Zn), and lead. A number of different coordination modes is found, including unexpected motifs such as the κ3O1,4,7 coordination in the lead salt and anions of the type [M(H2O)4(κ2O1,4‐mts)]− (M=Co, Ni, Zn), which do not seem to be persistent in aqueous solution.
