ScRe2Si crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two ScRe2Si clusters. Sc(1) is bonded in a single-bond geometry to two equivalent Re(1) and one Si(1) atom. Both Sc(1)-Re(1) bond lengths are 1.38 Å. The Sc(1)-Si(1) bond length is 0.93 Å. Re(1) is bonded in a 2-coordinate geometry to one Sc(1) and one Re(1) atom. The Re(1)-Re(1) bond length is 0.93 Å. Si(1) is bonded in a single-bond geometry to one Sc(1) atom.
