LaCoSb2 is Parent of FeAs superconductors-derived structured and crystallizes in the tetragonal P4/nmm space group. La(1) is bonded to four equivalent Co(1), four equivalent Sb(1), and four equivalent Sb(2) atoms to form a mixture of face, corner, and edge-sharing LaCo4Sb8 cuboctahedra. Co(1) is bonded in a 8-coordinate geometry to four equivalent La(1) and four equivalent Sb(2) atoms. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a 8-coordinate geometry to four equivalent La(1) and four equivalent Sb(1) atoms. In the second Sb site, Sb(2) is bonded in a 8-coordinate geometry to four equivalent La(1) and four equivalent Co(1) atoms.
