Refinement of the crystal structure of (NH₄)₄ [UO₂ (CO₃)₃]

Serezhkin, V.N.; Soldatkina, M.A.; Boiko, N.V.1984

AbstractAbstract

[en] The crystal structure of (NH₄)₄ [UO₂ (CO₃)₃] has been refined (CAD-4-SDP 55 diffractometer, lambdaMo, 1630 reflections, anisotropic MLS, R = 0.032), and the coordinates of the hydrogen atoms have been determined. The structure is made up of tetrahedral ammonium cations and mononuclear [UO₂(CO₃)₃]^4- anions, joined by hydrogen bonds. The coordination polyhedron of the U atom is a hexagonal bipyramid UO₂O₆ (U-O₂O₆/sux ax/ = 1.790, U-O/sub eq/ = 2.438-2.442 A). 12 references, 2 figures, 3 tables
