The crystal structure of (NH/sub 4/)/sub 4/ (UO/sub 2/ (CO/sub 3/)/sub 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 (UO/sub 2/(CO/sub 3/)/sub 3/)/sup 4 -/ anions, joined by hydrogen bonds. The coordination polyhedron of the U atom is a hexagonal bipyramid UO/sub 2/O/sub 6/ (U-O/sub 2/O/sub 6//sux ax/ = 1.790, U-O/sub eq/ = 2.438-2.442 A). 12 references, 2 figures, 3 tables.
