La2MnSb4 crystallizes in the tetragonal P-4m2 space group. La(1) is bonded in a 10-coordinate geometry to two equivalent Mn(1), two equivalent Sb(2), two equivalent Sb(3), and four equivalent Sb(1) atoms. Mn(1) is bonded to four equivalent La(1) and four equivalent Sb(1) atoms to form distorted edge-sharing MnLa4Sb4 tetrahedra. There are three inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a 6-coordinate geometry to four equivalent La(1) and two equivalent Mn(1) atoms. In the second Sb site, Sb(2) is bonded in a 8-coordinate geometry to four equivalent La(1) and four equivalent Sb(3) atoms. In the third Sb site, Sb(3) is bonded in a 8-coordinate geometry to four equivalent La(1) and four equivalent Sb(2) atoms.
