Synthesis and crystal structure of [UO2CrO4(C5NH5COO)] · 0.25H2O

, Z = 2, and R = 0.026. The structure is built of [UO2CrO4(C5NH5COO)2(H2O)]2 centrosymmetric dimers, which are linked into a framework by a system of hydrogen bonds involving inner-sphere and outer-sphere water molecules. The coordination number of the U(VI) atom is seven, and the coordination polyhedron is a pentagonal bipyramid with the oxygen atoms of the uranyl group, two chromate groups, two molecules of isonicotinic acid, and a water molecule at the vertices. The crystal chemical formula of the [UO2CrO4(C5NH5COO)2(H2O)]2 dimer is represented as AB2M31, where AB2M31, where A = UO22+, B2 = CrO42−, and M1 = = C5NH4COOH and H2O.
