Abstract
The title compound, (NH4)ZnPO4-HEX, is built up from a three-dimensional ne twork of ZnO4 and PO4 tetrahedra [d(av) (Zn-O) = 1.9400 (7) Angstrom and d( av) (P-O) = 1.5396 (7) Angstrom], fused together via Zn-O-P links [theta (a v) = 133.47 (4)degrees]. An undisordered linear Zn-O-P bond occurs (all thr ee atoms lie on a threefold axis). Extra-framework NH4+ cations, which inte ract with the [ZnPO4](-) framework by hydrogen bonds, complete the crystal structure.
