The structure described by Yb4As3 crystallizes in the cubic I-43d space group. Yb(1) is bonded to six equivalent As(1) atoms to form a mixture of distorted edge, corner, and face-sharing YbAs6 octahedra. The corner-sharing octahedral tilt angles range from 18-49°. As(1) is bonded to eight equivalent Yb(1) atoms to form a mixture of distorted edge, corner, and face-sharing AsYb8 hexagonal bipyramids. is represented by the CIF file [CIF]
