An organically templated yttrium fluoride with a 'super-diamond' structure

摘要

An organically templated yttrium fluoride has been prepared hydrothermally and characterised by X-ray powder diffraction. The crystal structure of [C3N2H12](0.5)[Y3F10] may be regarded as a 'Super-Diamond' framework, space group F d(3) over bar m, a = 15.4817(1) angstrom, where each carbon atom site of the diamond structure is replaced by a polyhedral [Y6F8F24/2](2-) unit. The basic framework type is isostructural with the known phase (H3O)[Yb3F10]center dot H2O. The novelty in the present case lies in the use of the organic structure-directing agent 1,3-diaminopropane. (c) 2006 Elsevier Inc. All rights reserved.
