摘要：

The synthesis and crystal structure of a new microporous zincophosphate are described. [H2N2C6H16](0.5)[Zn-2(PO4)(HPO4)(H2O)]. H2O crystallizes in the triclinic space group <P(1)over bar> with a = 8.822(4), b = 9.236(4), c = 8.451(3) Angstrom, alpha = 67.19(3), beta = 91.32(3), gamma = 111.10(3)degrees, V = 586.7(4) Angstrom(3) and Z = 2. This new material consists of infinite two-dimensional anionic layers alternated with planes containing organic diprotonated templates, N, N, N', N'-tetramethylethylenediamine [H2N2C6H16](2+) molecules. The framework structure is built up of ZnO4, ZnO3OH2, PO4, and PO3OH tetrahedra, linked through oxygen vertices. The presence of terminal OH2 and OH groups, leads to an open structure containing four- and eight-rings. The organic molecules are interconnected to the framework through hydrogen bonds.
