LaCuTeS crystallizes in the monoclinic P2_1/c space group. La(1) is bonded in a 4-coordinate geometry to four equivalent Te(1) and four equivalent S(1) atoms. Cu(1) is bonded in a 1-coordinate geometry to three equivalent Te(1) and one S(1) atom. Te(1) is bonded in a 7-coordinate geometry to four equivalent La(1) and three equivalent Cu(1) atoms. S(1) is bonded to four equivalent La(1) and one Cu(1) atom to form a mixture of edge and corner-sharing SLa4Cu trigonal bipyramids.
