Attempts to synthesize Sb-based analogues of the known Bi-based Aurivillius phase, Bi3TiNbO9, have led to the discovery of an isomorphous pair of a new type of layered intergrowth phase of general stoichiometry Sb3+x Nb3−x TiO14 and Sb3+x Ta3−x TiO14. Electron diffraction proved essential for the initial recognition and structural characterization of these phases. The structures of Sb3+x Nb3−x TiO14, x = 0.89, and Sb3+x Ta3−x TiO14, x = 1.26, are reported. The structures are described as ordered intergrowths of β-Sb2O4-type and Sb2O5-type structures, with NbV/TaV substituting for SbV in the former and NbV/TaV/TiIV substituting for SbV in the latter.

Metal glycinate chelates are formed by glycine and metal compounds through chemical reactions. Calcium glycinate, magnesium glycinate and zinc glycinate are kinds of new-type and ideal nutrient supplements, which have satisfactory physico-chemical properties and bioactivities. They are important for prophylaxis and treat metal deficiency. The structural characterization shows that the metal ion is bonded to the amino and carboxyl group to form two five-membered rings. This paper mainly studies the structure characterization of the metal chelated glycinates by their solubility, infrared spectrum, thermal analysis, mass spectrometry, polycrystal diffraction, the metal contents and glycine contents of calcium glycinate, magnesium glycinate and zinc glycinate.
