Abstract
A new open-framework zincophosphate, (C 2N 2H 10) 2[Zn(PO 4) 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 P ccn, a = 17.056(3) Å, b = 8.4219(17) Å, c = 8.7260(18) Å, V = 1253.4(4) Å 3, Z = 4. The crystal structure of the title compound is characterized by corner-sharing PO 4 and ZnO 4 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 (C 2N 2H 10) 2[Zn(PO 4) 2] shows an emission band between 665 nm and 688 nm when excited with 451 nm UV light.
