✦ Synopsis

Nanoporous Titanium Borophosphates with Rigid Gainesite-Type Framework Structure. -Nanoporous titanium borophosphates [B(PO4)4]}•xH2O (M: Li, Na, K, Rb, Cs, NH4, H3O; 0 ≤ x ≤ 1) are hydrothermally synthesized by reaction of Ti in HCl solution with boric acid and the respective alkali metal phosphate (autoclave, 453 K, 3 d). The isotypic compounds crystallize in the tetragonal space group I41/amd with Z = 2 (single crystal XRD) and show a close structural relation to the mineral gainesite, Na2Zr2[Be(PO4)4]. The open-framework character of the materials is supported by the reversibility of de-and rehydration processes. -(KNIEP*, R.; et al.;
