The material structure described by 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. is represented by the CIF card [CIF]
