摘要

In the system ZnO/H3PO4/H2O/1,4-diazacycloheptane (C5H12N2), a new zincophosphate (ZnPO), (C5H14N2)[Zn-3(HPO4)(4)] (I), was prepared by hydrothermal transformation (180 degrees C) of the known ZnPO hydrate (C5H14N2)[Zn-2(HPO4)(3)]center dot H2O (II). The thermally-induced transformation is reversible; upon keeping the heterogeneous mixture of I and mother liquor at 80 degrees C recrystallization of II was observed. Single-crystal X-ray crystallography revealed that I possesses a unique three-dimensional (3D) open-framework structure built from corner-linked ZnO4 and HPO4 tetrahedra. The (3,4)-connected framework of I differs considerably from the 3D open-framework ZnPO structure of II. Crystal data for I: Monoclinic system, space group Cc (No. 9), Z = 4, a = 9.1389(6), b = 23.627(2), c = 9.3073(6) angstrom, beta = 109.463(7)degrees T = 298 K.
