Ta4Ga(TeSe)4 crystallizes in the cubic F-43m space group. Ta(1) is bonded in a 6-coordinate geometry to three equivalent Te(1) and three equivalent Se(1) atoms. Ga(1) is bonded in a tetrahedral geometry to four equivalent Te(1) atoms. Te(1) is bonded to three equivalent Ta(1) and one Ga(1) atom to form a mixture of edge and corner-sharing TeTa3Ga tetrahedra. Se(1) is bonded in a 3-coordinate geometry to three equivalent Ta(1) atoms.
