摘要: An organically templated yttrium fluoride has been prepared hydrothermally and characterised by X-ray powder diffraction. The crystal structure of [C{sub 3}N{sub 2}H{sub 12}]{sub 0.5}[Y{sub 3}F{sub 10}] may be regarded as a 'Super-Diamond' framework, space group Fd3-bar m, a=15.4817(1)A, where each carbon atom site the diamond is replaced polyhedral [Y{sub 6}F{sub 8}F{sub 24/2}]{sup 2-} unit. basic framework type isostructural with known phase (H{sub 3}O)[Yb{sub 10}].H{sub 2}O. novelty in present case lies use organic structure-directing agent 1,3-diaminopropane.
