Re Si Rh Rh
ReRh2Si crystallizes in the triclinic P1 space group. Re(1) is bonded in a single-bond geometry to one Rh(2), two equivalent Rh(1), and one Si(1) atom. The Re(1)-Rh(2) bond length is 0.35 Å. There is one shorter (1.73 Å) and one longer (2.62 Å) Re(1)-Rh(1) bond length. The Re(1)-Si(1) bond length is 1.10 Å. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a 5-coordinate geometry to two equivalent Re(1), one Rh(2), and two equivalent Si(1) atoms. The Rh(1)-Rh(2) bond length is 1.74 Å. There is one shorter (1.93 Å) and one longer (3.12 Å) Rh(1)-Si(1) bond length. In the second Rh site, Rh(2) is bonded in a single-bond geometry to one Re(1), one Rh(1), and two equivalent Si(1) atoms. There is one shorter (1.26 Å) and one longer (2.63 Å) Rh(2)-Si(1) bond length. Si(1) is bonded in a 5-coordinate geometry to one Re(1), two equivalent Rh(1), and two equivalent Rh(2) atoms.
