Abstrakt

The structure of the title compound, ammineaquadi-_5-phosphato-trizinc(II), [Zn3(PO4)2(H2O)0.8(NH3)1.2], consistsof two parts: (i) PO4 and ZnO4 vertex-sharing tetrahedraarranged in layers parallel to (100) and (ii) ZnO2(N/O)2tetrahedra located between the layers. Elemental analysisestablishes the ammine-to-water ratio as 3:2. ZnO2(N/O)2tetrahedra are located at special position 4e (site symmetry 2)in C2/c. The two O atoms of ZnO2(N/O)2 are bonded toneighbouring P atoms, forming two Zn-O-P linkages andconnecting ZnO2(N/O)2 tetrahedra with two adjacent bc planelayers. A noteworthy feature of the structure is the presence ofNH3 and H2O at the same crystallographic position and,consequently, qualitative changes in the pattern of hydrogenbonding and weaker N/O-H__O electrostatic interactions, ascompared to two closely related structures.
