Bi2Te2S crystallizes in the triclinic P-1 space group. Bi(1) is bonded in a distorted single-bond geometry to five equivalent Te(1) and one S(1) atom. Te(1) is bonded to five equivalent Bi(1) atoms to form a mixture of distorted edge and corner-sharing TeBi5 trigonal bipyramids. S(1) is bonded in a linear geometry to two equivalent Bi(1) atoms.
