Title: New open-framework in the uranyl vanadates A{sub 3}(UO{sub 2}){sub 7}(VO{sub 4}){sub 5}O (A=Li, Ag) with intergrowth structure between A(UO{sub 2}){sub 4}(VO{sub 4}){sub 3} and A{sub 2}(UO{sub 2}){sub 3}(VO{sub 4}){sub 2}O

Abstract

New uranyl vanadates A{sub 3}(UO{sub 2}){sub 7}(VO{sub 4}){sub 5}O (M=Li (1), Na (2), Ag (3)) have been synthesized by solid-state reaction and their structures determined from single-crystal X-ray diffraction data for 1 and 3. The tetragonal structure results of an alternation of two types of sheets denoted S for {sub {infinity}}{sup 2}[UO{sub 2}(VO{sub 4}){sub 2}]{sup 4-} and D for {sub {infinity}}{sup 2}[(UO{sub 2}){sub 2}(VO{sub 4}){sub 3}]{sup 5-} built from UO{sub 6} square bipyramids and connected through VO{sub 4} tetrahedra to {sub {infinity}}{sup 1}[U(3)O{sub 5}-U(4)O{sub 5}]{sup 8-} infinite chains of edge-shared U(3)O{sub 7} and U(4)O{sub 7} pentagonal bipyramids alternatively parallel to a- and b-axis to construct a three-dimensional uranyl vanadate arrangement. It is noticeable that similar {sub {infinity}}[UO{sub 5}]{sup 4-} chains are connected only by S-type sheets in A{sub 2}(UO{sub 2}){sub 3}(VO{sub 4}){sub 2}O and by D-type sheets in A(UO{sub 2}){sub 4}(VO{sub 4}){sub 3}, thus A{sub 3}(UO{sub 2}){sub 7}(VO{sub 4}){sub 5}O appears as an intergrowth structure between the two previously reported series. The mobility of the monovalent ion in the mutually perpendicular channels created in the three-dimensional arrangement is correlated to the occupation rate of the sites and by the geometry of the different sites occupied by either Na, Ag ormore » Li.
