title: Chelating of titanium by lactic acid in the water-soluble diammonium tris(2-hydroxypropionato)titanate(IV).
abstract: Stable water-soluble diammonium tris(2-hydroxypropionato)titanate(IV) [ammonium trilactatotitanate(IV)], (NH4)2[Ti(C3H4O3)3], was prepared in the crystalline form. According to the X-ray single-crystal diffraction data, this compound crystallizes in the cubic cell with a = 11.649(4) angstroms, space group P2(1)3 (no. 198), and has Z = 4 molecules per unit cell. The 13C NMR data and Raman and IR spectra support the determined structure. The absence of nonbonded functional groups restricts the formation of oligomers in contrast to the reported speciation of citratoperoxotitanate(IV) complexes.
