Abstract

The synthesis and single crystal structure of Na(3/)4(NH4)(1/4)ZnPO4, a new sodium-ammonium zinc phosphate, are reported. This phase adopts a previously unseen tetrahedral topology and is built up from a three-dimensional network of ZnO4 [d(av)(Zn-O) = 1.952(2) Angstrom] and PO4 [d(av)(P-O) = 1.538(2) Angstrom] units, fused together via Zn-O-P links [theta(av) = 125.1(1)degrees]. Extra-framework Na+ and NH4+ cations complete the crystal structure. The tetrahedral topology of this phase may be described as being built up from 6(3) hexagonal sheets containing two types (SSCSSC and SSSCSC) of six-rings arrayed normal to [100]. The crystal structures of related MZnPO4 type phases (M = univalent cation) are reviewed. Crystal data: Na-3/4(NH4)(1/4)ZnPO4, M-r = 364.23, orthorhombic, space group Pbcn (No. 60), a = 8.251(2) Angstrom, b = 10.371(3) Angstrom, c = 17.430(3) Angstrom, V = 1491.4(6) Angstrom(3), Z = 16, R = 2.71%, R-w = 2.56% [133 parameters, 1585 observed reflections with I > 3 sigma(I)].
