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.
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. There are six shorter (3.00 Å) and six longer (3.16 Å) Ho(1)-As(1) bond lengths. As(1) is bonded in a 6-coordinate geometry to four equivalent Ho(1) and two equivalent As(1) atoms. Both As(1)-As(1) bond lengths are 2.75 Å.
