The material structure described by La2Sb crystallizes in the tetragonal I4/mmm space group. There are two inequivalent La sites. In the first La site, La(1) is bonded to five equivalent Sb(1) atoms to form a mixture of distorted corner and edge-sharing LaSb5 trigonal bipyramids. In the second La site, La(2) is bonded in a 8-coordinate geometry to four equivalent La(2) and four equivalent Sb(1) atoms. Sb(1) is bonded in a 9-coordinate geometry to four equivalent La(2) and five equivalent La(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
