The crystal structure described by K3GaTe3 crystallizes in the monoclinic P2_1/c space group. There are three inequivalent K sites. In the first K site, K(1) is bonded in a 5-coordinate geometry to one Te(1), two equivalent Te(2), and two equivalent Te(3) atoms. In the second K site, K(2) is bonded in a 8-coordinate geometry to one Ga(1), two equivalent Te(1), two equivalent Te(2), and three equivalent Te(3) atoms. In the third K site, K(3) is bonded in a 5-coordinate geometry to two equivalent Te(1), two equivalent Te(2), and two equivalent Te(3) atoms. Ga(1) is bonded to one K(2), one Te(2), one Te(3), and two equivalent Te(1) atoms to form distorted GaKTe4 tetrahedra that share corners with two equivalent Te(2)K6Ga pentagonal bipyramids and  an edgeedge with one Ga(1)KTe4 tetrahedra. There are three inequivalent Te sites. In the first Te site, Te(1) is bonded in a 7-coordinate geometry to one K(1), two equivalent K(2), two equivalent K(3), and two equivalent Ga(1) atoms. In the second Te site, Te(2) is bonded to two equivalent K(1), two equivalent K(2), two equivalent K(3), and one Ga(1) atom to form distorted TeK6Ga pentagonal bipyramids that share corners with two equivalent Te(2)K6Ga pentagonal bipyramids, corners with two equivalent Ga(1)KTe4 tetrahedra, and edges with two equivalent Te(2)K6Ga pentagonal bipyramids. In the third Te site, Te(3) is bonded in a 8-coordinate geometry to two equivalent K(1), two equivalent K(3), three equivalent K(2), and one Ga(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
