Abstract
(NH4)2[Bi2(C6H4O2)4].(C6H6O2)2.2H2O, a bismuth(III)-catechol complex adduct, has been prepared and its structure determined by X-ray diffraction methods. The complex anion is a centrosymmetric dimer comprising two five-coordinate [ bis ( catecholato (2-)) bismuthate (III)] centres [Bi-O, 2.177(4), 2.222(4) Ǻ and 2.150(3), 2.322(4)Ǻ], bridged by one of the catechol oxygens [Bi-O, 2.653(3)Ǻ]. In addition, the structure is stabilized by hydrogen bonding involving the ammonium ions, the lattice waters and the two adduct catechol molecules.
