The material structure described by La3TiSb5 crystallizes in the hexagonal P6_3/mcm space group. La(1) is bonded in a 9-coordinate geometry to four equivalent Sb(1) and five equivalent Sb(2) atoms. Ti(1) is bonded to six equivalent Sb(2) atoms to form face-sharing TiSb6 octahedra. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a 8-coordinate geometry to six equivalent La(1) and two equivalent Sb(1) atoms. In the second Sb site, Sb(2) is bonded to five equivalent La(1) and two equivalent Ti(1) atoms to form a mixture of distorted edge, corner, and face-sharing SbLa5Ti2 pentagonal bipyramids. is represented by the Crystallographic Information File (CIF) [CIF]
