LaAs3 crystallizes in the hexagonal P6_3/mmc space group. La(1) is bonded to twelve equivalent As(1) atoms to form a mixture of distorted face and corner-sharing LaAs12 cuboctahedra. As(1) is bonded in a 6-coordinate geometry to four equivalent La(1) and two equivalent As(1) atoms.
LaAs3 crystallizes in the hexagonal P6_3/mmc space group. La(1) is bonded to twelve equivalent As(1) atoms to form a mixture of distorted face and corner-sharing LaAs12 cuboctahedra. There are six shorter (3.18 Å) and six longer (3.26 Å) La(1)-As(1) bond lengths. As(1) is bonded in a 6-coordinate geometry to four equivalent La(1) and two equivalent As(1) atoms. Both As(1)-As(1) bond lengths are 2.56 Å.
