摘要:
Anew open-framework zincophosphate, (C2N2H10)(2)[Zn(PO4)(2)], has been synthesized hydrothermally from a mixture of zinc chloride, phosphoric acid, ethylenediamine and deionized water. It has the following crystal data: orthorhombic space group Pccn, a = 17.056(3) angstrom, b = 8.4219(17) angstrom, c = 8.7260(18) angstrom, V= 1253.4(4) angstrom(3), Z = 4. The crystal structure of the title compound is characterized by corner-sharing PO4 and ZnO4 tetrahedra, leading to infinite corner-shared four-membered ring chains. There is extensive Zn-O-P bonding in the structure in the form of infinite chains. The structure is stabilized by template-to-framework hydrogen bonding. The title compound was also characterized by IR spectroscopy and TG-DTA. Luminescent measurement of (C2N2H10)(2)[Zn(PO4)(2)] shows an emission band between 665 nm and 688 nm when excited with 451 nm UV light. (C) 2007 Elsevier B.V. All rights reserved.
