Ti[BP2O7(OH)3]: The first titanium borophosphate containing novel anionic partial structure†
Abstract
The first titanium borophosphate Ti[BP2O7(OH)3] has been hydrothermally synthesized and structurally characterized. The compound has a three-dimensional open-framework architecture by linking TiO6 octahedra to the anionic layers [BP2O7(OH)3]4− which are built up from BO3(OH) tetrahedra and PO3(OH) tetrahedra. The compound not only represents the first transition metal titanium(IV) borophosphate but also displays the novel two-dimensional layered borophosphate anionic partial structure.
