An organouranium coordination polymer containing infinite metal oxide chains.
The title compound, catena-poly[[[dioxouranium(VI)]-bis(micro-2-hydroxybenzohydroxamato)] dihydrate], [[U(C(7)H(6)NO(3))(2)O(2)].2H(2)O](n), is a uranyl coordination polymer based on the salicylhydroxamate ligand. The ligand acts both as a chelate, forming five-membered rings, and as a bridge between two U atoms. The coordination around each U atom is a distorted hexagonal bipyramid. Infinite chains running along [001] are formed via bridging salicylhydroxamate O atoms. The chains have C(2) symmetry, with U atoms in special positions on twofold axes. The water molecules are not coordinated to the metal but crosslink, through hydrogen bonding, adjacent coordination polymer chains in the [110] and [110] directions.
