Structure studies on actinides carboxylates. 6. Crystal structures of strontium uranyldimalonate trihydrate and barium uranyldimalonate trihydrate

Abstract

SrUO/sub 2/(C/sub 3/H/sub 2/O/sub 4/)/sub 2/.3H/sub 2/O and BaUO/sub 2/(C/sub 3/H/sub 2/O/sub 4/).3H/sub 2/O are isostructural. They crystallize in the orthorhombic system space group Pbca with eight molecules in cells of dimensions a = 16.729(8), b = 23.247(11) and c = 6.848(5) A and a = 17.063(9), b = 23.604(12) and c = 6.885(5) A, respectively. The structures were solved by the heavy-atom technique and refined with full-matrix least-squares to the R values of 0.043 and 0.046, respectively. The coordination geometry around the uranium atom is a pentagonal bipyramid with the malonates behaving as bidentate or terdentate ligands to the uranium atoms forming polymeric chains (UO/sub 2/(C/sub 3/H/sub 2/O/sub 4/)/sub 2/)sub(n)sup(2n-) parallel to c. The space between the uranyl dimalonate chains is occupied by the oxygen atoms belonging either to the water molecules or to the carboxylic groups. Each polyhedron shares two edges forming columns running in the same direction as the uranyl chains and connecting them four by four.
