YAs3 crystallizes in the hexagonal P6_3/mmc space group. Y(1) is bonded to twelve equivalent As(1) atoms to form a mixture of distorted corner and face-sharing YAs12 cuboctahedra. As(1) is bonded in a 6-coordinate geometry to four equivalent Y(1) and two equivalent As(1) atoms.
YAs3 crystallizes in the hexagonal P6_3/mmc space group. Y(1) is bonded to twelve equivalent As(1) atoms to form a mixture of distorted corner and face-sharing YAs12 cuboctahedra. There are six shorter (3.02 Å) and six longer (3.18 Å) Y(1)-As(1) bond lengths. As(1) is bonded in a 6-coordinate geometry to four equivalent Y(1) and two equivalent As(1) atoms. Both As(1)-As(1) bond lengths are 2.66 Å.
