Using THF and water as solvent, piperazine as a template, a novel two dimensional layered zinc phosphate 1.5[Zn2(PO4)(HPO4)2]·H2O has been prepared solvothermally, and its structure is determined at 293K by Siemens Smart 1000 CCD diffractometer monoclinic, P21/c, a=0.81244(3)nm, b=2.61706(12)nm, c=0.83775(3)nm, β=110.981(2)°, V=1.66313(11)nm3, Z=4, R=0.0285, wR=0.0719. The structure con sists of vertex sharing ZnO4, HPO4, and PO4 tetrahedra, and double protonated organic cations, which results in formation of undulating 4 ring chains and 12 ring sheets. A network of hydrogen bonds involving both layer to layer and layer to amine interaction holds the phosphate layer together. CCDC: 200374.
