Abstract

The bismuth(III) complex of thiosalicylic acid (2-mercaptobenzoic acid; H₂L), ammonium tris(2-mercaptobenzoato-O,S) bismuth(III) dihydrate, {(NH₄)₃[Bi(L)₃]·2 H₂O}, has been prepared and its crystal structure determined. The distorted octahedral tris-bidentate complex unit has pseudo-C₃ symmetry with the facially related thiolate sulfur donors providing a regular facial cap to the octahedron (Bi–S 2.595, 2.596, 2.596(5) Å) with the Bi–O(carboxylate) distances less regular (2.715, 2.741, 2.785(15) Å). The network polymeric structure is stabilized by hydrogen-bonding associations through both the ammonium counter ions and the lattice water molecules.
