catena-Poly[[aqua­dioxidouranium(VI)]-μ(3)-4,4′-oxydibenzoato]

The title compound, [UO(2)(C(14)H(8)O(5))(H(2)O)](n), is a polymeric UO(2) complex bridged by 4,4′-oxydibenzoate ligands. One carboxyl­ate group of the bridging ligand chelates a uranyl cation while the other carboxyl­ate group of the ligand bridges two other two uranyl cations, forming a double-cha...

Descripción
Sumario:The title compound, [UO(2)(C(14)H(8)O(5))(H(2)O)](n), is a polymeric UO(2) complex bridged by 4,4′-oxydibenzoate ligands. One carboxyl­ate group of the bridging ligand chelates a uranyl cation while the other carboxyl­ate group of the ligand bridges two other two uranyl cations, forming a double-chain polymeric structure. The central U(VI) atom is seven-coordin­ated in a distorted UO(7) penta­gonal-bipyramidal geometry. In the crystal structure, O—H⋯O hydrogen bonding links the polymeric chains into a three-dimensional supra­molecular framework. Within the bridging ligand, the two benzene rings are oriented at a dihedral angle of 59.0 (2)°.
