摘要：

The hydrothermal synthesis and single crystal structure determination of a new open-framework zinc phosphate, [NH3(CH2)(3)NH3](2)[NH3(CH2)(3)NH2](2)[Zn-12(OH2)(2)(PO4)(10)]. H2O, is reported. Crystal data: monoclinic, space group Pn (no. 7), a=13.092(2), b=14.272(2), c=14.220(1) Angstrom, beta=90.3(2)degrees, V=2656.9(1) Angstrom(3), Z=2, M=1927.6, R=0.04. The structure is made up of tetrahedral linkages between ZnO4, ZnO3N and PO4 moieties forming distinct channels. The structure-directing amine is present in two distinct forms, in the free state and as a ligand to zinc, the two species occurring in distinct channels.
