Аннотация:New Strontium titanyl phosphate Sr2TiO(PO4)(2) (1) was synthesized and characterized by X-ray powder diffraction, electron diffraction, high-resolution electron microscopy, and band structure calculations. Titanyl phosphate 1 is isostructural with vanadyl phosphate Sr2VO(PO4)(2) and has a layered structure. The titanium atoms are shifted from the centers of the TiO6 octahedra and form short (1.74 angstrom) titanyl bonds. The Structure of 1 is an unusual example of the disordered orientation of the chains formed by TiO6 octahedra in complex titanium phosphates.
