Abstract: The X-ray powder diagrams of four compounds in the system NH3UO3H2O have been indexed. The following results were obtained: I: β-UO3·2H2O; orthorhombic; a = 13·977 ± 0·004 Å; b = 16·696 ± 0·004 Å; c = 14·672 ± 0·004 Å. II: 3UO3·NH3·5H2O; orthorhombic; a = 7·220 ± 0·003 Å; b = 12·198 ± 0·003 Å; c = 15·072 ± 0·004 Å. III: 2UO3·NH3·3H2O; hexagonal; a = 14·087 ± 0·004 Å; c = 14·494 ± 0·005 Å; IV: 3UO3·2NH3·4H2O; hexagonal; a = 4·031 ± 0·004 Å; c = 14·58 ± 0·001 Å The structures consist of hexagonal or pseudohexagonal layers of composition UO2(O2)∞, with the additional O and N atoms of water and ammonia between these layers.
