Abstract:
The title compound, (NH(4))ZnPO(4)-HEX, is built up from a three-dimensional network of ZnO(4) and PO(4) tetrahedra [d(av)(Zn-O) = 1.9400 (7) A and d(av)(P-O) = 1.5396 (7) A], fused together via Zn-O-P links [straight theta(av) = 133.47 (4) degrees ]. An undisordered linear Zn-O-P bond occurs (all three atoms lie on a threefold axis). Extra-framework NH(4)(+) cations, which interact with the [ZnPO(4)](-) framework by hydrogen bonds, complete the crystal structure.
