Title: Hydrothermal synthesis, crystal structure, and characterization of a new pseudo-two-dimensional uranyl oxyfluoride, [N(C{sub 2}H{sub 5}){sub 4}]{sub 2}[(UO{sub 2}){sub 4}(OH{sub 2}){sub 3}F{sub 10}]

Abstract

A new uranyl oxyfluoride, [N(C{sub 2}H{sub 5}){sub 4}]{sub 2}[(UO{sub 2}){sub 4}(OH{sub 2}){sub 3}F{sub 10}] has been synthesized by a hydrothermal reaction technique using (C{sub 2}H{sub 5}){sub 4}NBr, UO{sub 2}(OCOCH{sub 3}){sub 2}.2H{sub 2}O, and HF as reagents. The structure of [N(C{sub 2}H{sub 5}){sub 4}]{sub 2}[(UO{sub 2}){sub 4}(OH{sub 2}){sub 3}F{sub 10}] has been determined by a single-crystal X-ray diffraction technique. [N(C{sub 2}H{sub 5}){sub 4}]{sub 2}[(UO{sub 2}){sub 4}(OH{sub 2}){sub 3}F{sub 10}] crystallizes in the monoclinic space group P2{sub 1}/n (No. 14), with a=13.852(3)A, b=15.532(3)A, c=16.481(3)A, {beta}=98.88(3){sup o}, V=3503.4(12)A{sup 3}, and Z=4. [N(C{sub 2}H{sub 5}){sub 4}]{sub 2}[(UO{sub 2}){sub 4}(OH{sub 2}){sub 3}F{sub 10}] reveals a novel pseudo-two-dimensional crystal structure that is composed of UO{sub 2}F{sub 5}, UO{sub 3}F{sub 4}, and UO{sub 4}F{sub 3} pentagonal bipyramids. Each uranyl pentagonal bipyramid shares edges and corners through F atoms to form a six-membered ring. The rings are further interconnected to generate infinite strips running along the b-axis. [N(C{sub 2}H{sub 5}){sub 4}]{sub 2}[(UO{sub 2}){sub 4}(OH{sub 2}){sub 3}F{sub 10}] has been further characterized by elemental analysis, bond valence calculations, Infrared and Raman spectroscopy, and thermogravimetric analysis.
