Synthesis and crystal structure of calcium dizinc iron(III) tris-(orthophosphate), CaZn₂Fe(PO₄)₃.

ABSTRACT: Single crystals of the title compound, CaZn₂Fe(PO₄)₃, were synthesized by conventional solid-state reaction. In the asymmetric unit, all atoms are located in fully occupied general positions of the P2₁/c space group. The zinc atoms are located on two crystallographically independent sites with tetra-hedral and distorted triangular-based bipyramidal geometries. Two edge-sharing triangular bipyramidal ZnO₅ units form a dimer, which is linked to slightly deformed FeO₆ octa-hedra via a common edge. The resulting chains are inter-connected through PO₄ tetra-hedra to form a layer perpendicular to the b axis. Moreover, the remaining PO₄ and ZnO₄ tetra-hedra are linked tog
