The structure described by HoAs3 crystallizes in the hexagonal P6_3/mmc space group. Ho(1) is bonded to twelve equivalent As(1) atoms to form a mixture of face and corner-sharing HoAs12 cuboctahedra. As(1) is bonded in a 6-coordinate geometry to four equivalent Ho(1) and two equivalent As(1) atoms. is represented by the CIF card [CIF]
