Materials Data on Th3As4 by Materials Project
Th3As4 crystallizes in the cubic I-43d space group. The structure is three-dimensional. Th4+ is bonded to eight equivalent As3- atoms to form a mixture of distorted face, edge, and corner-sharing ThAs8 hexagonal bipyramids. There are four shorter (3.04 Å) and four longer (3.12 Å) Th–As bond lengths. As3- is bonded to six equivalent Th4+ atoms to form a mixture of distorted face, edge, and corner-sharing AsTh6 octahedra. The corner-sharing octahedra tilt angles range from 15–51°.
