Solvothermal Conditions

The title compound, ammonium catena-[monoboro-monodihydrogendiborate-monohydrogenphosphate] hemihydrate, was obtained under solvothermal conditions using glycol as the solvent. The crystal structure is constructed of one-dimensional infinite borophosphate chains, which are interconnected by ammonium ions and water molecules via a complex hydrogen-bond network to form a three-dimensional structure. The water molecules of crystallization are disordered over inversion centres, and their H atoms were not located.

ABSTRACTA pure form of the compound [(CH3)4N]0.2Mn0.06V2O5+δ•0.2H2O has been synthesized by the hydrothermal technique. A manganese richer compound, [(CH3)4N]0.18Mn0.1V2O5+δ•0.35H2O, has also been synthesized. By comparison to [(CH3)4N]0.17Fe0.1V2O5+δ•0.17H2O, the structure of these compounds consists of double sheets of vanadium oxide with tetramethyl ammonium ions in the interlayer spaces. Both compounds display reversible lithium intercalation with sharp end points. The lithiation capacity is lowered by the increase in manganese content.

Catecholate Complex

(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.
