Topotactic Oxidation of TiGaPO-1, a Pyridine-Templated Titanium Gallophosphate with a New Octahedral-Tetrahedral 3-D Framework Structure Containing
TiIII/Ti IV. — The first three-dimensional open-framework Ti—Ga phosphate complex
(III) crystallizes in the monoclinic space group P21 with Z = 2 (single crystal XRD).
The structure contains TiIIIO6, TiIVO6, GaO4, and PO4 polyhedra which form a network
of one-dimensional pores occupied by the pyridinium cations. Heating of (III) in air at
543 K results in the oxidation of TiIII to Ti IV with retention of the original framework
structure. — (CHIPPINDALE*, A. M.; GRIMSHAW, M. R.; POWELL, A. V.;
