LaGaSb2 crystallizes in the orthorhombic C222_1 space group. La(1) is bonded in a 10-coordinate geometry to two equivalent Ga(1), four equivalent Sb(1), and four equivalent Sb(2) atoms. Ga(1) is bonded in a 6-coordinate geometry to two equivalent La(1), two equivalent Ga(1), and two equivalent Sb(1) atoms. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded to four equivalent La(1) and two equivalent Ga(1) atoms to form a mixture of distorted edge and corner-sharing SbLa4Ga2 pentagonal pyramids. In the second Sb site, Sb(2) is bonded in a 8-coordinate geometry to four equivalent La(1) and four equivalent Sb(2) atoms.
