Materials Data on Pa3As4 by Materials Project
Pa3As4 crystallizes in the cubic I-43d space group. The structure is three-dimensional. Pa4+ is bonded to eight equivalent As3- atoms to form a mixture of distorted edge, face, and corner-sharing PaAs8 hexagonal bipyramids. There are four shorter (2.93 Å) and four longer (3.01 Å) Pa–As bond lengths. As3- is bonded to six equivalent Pa4+ atoms to form a mixture of distorted edge, face, and corner-sharing AsPa6 octahedra. The corner-sharing octahedra tilt angles range from 15–51°.
