The compound described by K2GaSb2 is Magnesium tetraboride-derived structured and crystallizes in the orthorhombic Pnma space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 8-coordinate geometry to one Ga(1), one Ga(2), one Sb(1), one Sb(4), two equivalent Sb(2), and two equivalent Sb(3) atoms. In the second K site, K(2) is bonded in a 7-coordinate geometry to one Ga(1), two equivalent Ga(2), one Sb(2), one Sb(3), two equivalent Sb(1), and two equivalent Sb(4) atoms. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 7-coordinate geometry to two equivalent K(1), two equivalent K(2), one Sb(1), one Sb(2), and one Sb(4) atom. In the second Ga site, Ga(2) is bonded in a 9-coordinate geometry to two equivalent K(1), four equivalent K(2), one Sb(1), one Sb(2), and one Sb(3) atom. There are four inequivalent Sb sites. In the first Sb site, Sb(3) is bonded in a 8-coordinate geometry to two equivalent K(2), four equivalent K(1), one Ga(2), and one Sb(4) atom. In the second Sb site, Sb(4) is bonded in a 8-coordinate geometry to two equivalent K(1), four equivalent K(2), one Ga(1), and one Sb(3) atom. In the third Sb site, Sb(1) is bonded in a 8-coordinate geometry to two equivalent K(1), four equivalent K(2), one Ga(1), and one Ga(2) atom.
