Materials Data on Pa3Sb4 by Materials Project
Pa3Sb4 crystallizes in the cubic I-43d space group. The structure is three-dimensional. Pa4+ is bonded to eight equivalent Sb3- atoms to form a mixture of distorted corner, edge, and face-sharing PaSb8 hexagonal bipyramids. There are four shorter (3.14 Å) and four longer (3.21 Å) Pa–Sb bond lengths. Sb3- is bonded to six equivalent Pa4+ atoms to form a mixture of distorted corner, edge, and face-sharing SbPa6 octahedra. The corner-sharing octahedra tilt angles range from 15–51°.
