The crystal structure described by LaTa3 crystallizes in the hexagonal P6_3/mmc space group. La(1) is bonded to twelve equivalent Ta(1) atoms to form a mixture of distorted face and corner-sharing LaTa12 cuboctahedra. Ta(1) is bonded in a 10-coordinate geometry to four equivalent La(1) and six equivalent Ta(1) atoms. is represented by the CIF card [CIF]
