SrSb3 is Uranium Silicide structured and crystallizes in the monoclinic Cm space group. Sr(1) is bonded to four equivalent Sb(2) and eight equivalent Sb(1) atoms to form a mixture of distorted corner and face-sharing SrSb12 cuboctahedra. There are a spread of Sr(1)-Sb(2) bond distances ranging from 2.96-3.91 Å. There are a spread of Sr(1)-Sb(1) bond distances ranging from 3.24-3.74 Å. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a 9-coordinate geometry to four equivalent Sr(1), two equivalent Sb(2), and three equivalent Sb(1) atoms. There is one shorter (3.24 Å) and one longer (3.28 Å) Sb(1)-Sb(2) bond length. There is one shorter (2.96 Å) and two longer (3.47 Å) Sb(1)-Sb(1) bond lengths. In the second Sb site, Sb(2) is bonded in a 8-coordinate geometry to four equivalent Sr(1) and four equivalent Sb(1) atoms.
