Sc4OsCl4 crystallizes in the monoclinic C2/c space group. There are two inequivalent Sc sites. In the first Sc site, Sc(1) is bonded to two equivalent Os(1), two equivalent Cl(1), and two equivalent Cl(2) atoms to form a mixture of distorted edge, face, and corner-sharing ScOs2Cl4 octahedra. The corner-sharing octahedral tilt angles range from 39-92°. In the second Sc site, Sc(2) is bonded in a 6-coordinate geometry to two equivalent Os(1), two equivalent Cl(1), and two equivalent Cl(2) atoms. Os(1) is bonded in a 8-coordinate geometry to four equivalent Sc(1) and four equivalent Sc(2) atoms. There are two inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a 4-coordinate geometry to two equivalent Sc(1) and two equivalent Sc(2) atoms. In the second Cl site, Cl(2) is bonded in a 4-coordinate geometry to two equivalent Sc(1) and two equivalent Sc(2) atoms.

The corner-sharing octahedral tilt angles range from 39-92°. There is one shorter (2.70 Å) and one longer (2.74 Å) Sc(1)-Os(1) bond length. There is one shorter (2.69 Å) and one longer (2.77 Å) Sc(1)-Cl(1) bond length. There is one shorter (2.76 Å) and one longer (2.78 Å) Sc(1)-Cl(2) bond length. In the second Sc site, Sc(2) is bonded in a 6-coordinate geometry to two equivalent Os(1), two equivalent Cl(1), and two equivalent Cl(2) atoms. There is one shorter (2.71 Å) and one longer (2.72 Å) Sc(2)-Os(1) bond length. There is one shorter (2.69 Å) and one longer (2.75 Å) Sc(2)-Cl(1) bond length.
