SrSb4Te crystallizes in the trigonal R3m space group. Sr(1) is bonded in a 10-coordinate geometry to three equivalent Sb(1), three equivalent Sb(2), and four equivalent Te(1) atoms. All Sr(1)-Sb(1) bond lengths are 3.62 Å. All Sr(1)-Sb(2) bond lengths are 3.82 Å. There are three shorter (3.89 Å) and one longer (3.91 Å) Sr(1)-Te(1) bond length. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a 2-coordinate geometry to one Sr(1), one Sb(2), two equivalent Sb(1), and two equivalent Te(1) atoms. The Sb(1)-Sb(2) bond length is 2.19 Å. Both Sb(1)-Sb(1) bond lengths are 1.26 Å. There is one shorter (3.45 Å) and one longer (3.47 Å) Sb(1)-Te(1) bond length. In the second Sb site, Sb(2) is bonded in a 6-coordinate geometry to three equivalent Sr(1) and three equivalent Sb(1) atoms. Te(1) is bonded in a 10-coordinate geometry to four equivalent Sr(1) and six equivalent Sb(1) atoms.
