Sr Te W W
SrW2Te crystallizes in the monoclinic Cm space group. Sr(1) is bonded in a single-bond geometry to one W(1) and one W(2) atom. The Sr(1)-W(1) bond length is 2.88 Å. The Sr(1)-W(2) bond length is 0.54 Å. There are two inequivalent W sites. In the first W site, W(1) is bonded in a distorted single-bond geometry to one Sr(1) and one Te(1) atom. The W(1)-Te(1) bond length is 3.25 Å. In the second W site, W(2) is bonded in a single-bond geometry to one Sr(1) and one Te(1) atom. The W(2)-Te(1) bond length is 3.25 Å. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded to one W(1); one W(2); and six Te(1,1) atoms to form a mixture of distorted edge and corner-sharing TeTe6W2 hexagonal bipyramids. All Te(1)-Te(1,1) bond lengths are 3.21 Å. In the second Te site, Te(1) is bonded to one W(1); one W(2); and six Te(1,1) atoms to form a mixture of distorted edge and corner-sharing TeTe6W2 hexagonal bipyramids. The Te(1)-W(1) bond length is 3.25 Å. The Te(1)-W(2) bond length is 3.25 Å. Both Te(1)-Te(1) bond lengths are 3.21 Å.
