Materials Data on U3P4 by Materials Project
U3P4 crystallizes in the cubic I-43d space group. The structure is three-dimensional. U4+ is bonded to eight equivalent P3- atoms to form a mixture of distorted face, edge, and corner-sharing UP8 hexagonal bipyramids. There are four shorter (2.80 Å) and four longer (2.86 Å) U–P bond lengths. P3- is bonded to six equivalent U4+ atoms to form a mixture of distorted face, edge, and corner-sharing PU6 octahedra. The corner-sharing octahedra tilt angles range from 15–51°.
