SiAs3 crystallizes in the hexagonal P6_3/mmc space group. Si(1) is bonded to twelve equivalent As(1) atoms to form a mixture of distorted corner and face-sharing SiAs12 cuboctahedra. As(1) is bonded in a 6-coordinate geometry to four equivalent Si(1) and two equivalent As(1) atoms.
SiAs3 crystallizes in the hexagonal P6_3/mmc space group. Si(1) is bonded to twelve equivalent As(1) atoms to form a mixture of distorted corner and face-sharing SiAs12 cuboctahedra. There are six shorter (2.98 Å) and six longer (2.99 Å) Si(1)-As(1) bond lengths. As(1) is bonded in a 6-coordinate geometry to four equivalent Si(1) and two equivalent As(1) atoms. Both As(1)-As(1) bond lengths are 2.61 Å.
