Sr Si Rh Rh
SrRh2Si crystallizes in the triclinic P1 space group. Sr(1) is bonded in a single-bond geometry to three equivalent Rh(1) and one Si(1) atom. There are a spread of Sr(1)-Rh(1) bond distances ranging from 2.94-3.65 Å. The Sr(1)-Si(1) bond length is 0.36 Å. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a 5-coordinate geometry to three equivalent Sr(1), one Rh(2), and one Si(1) atom. The Rh(1)-Rh(2) bond length is 1.76 Å. The Rh(1)-Si(1) bond length is 2.35 Å. In the second Rh site, Rh(2) is bonded in a distorted single-bond geometry to one Rh(1) and one Si(1) atom. The Rh(2)-Si(1) bond length is 1.47 Å. Si(1) is bonded in a distorted single-bond geometry to one Sr(1), one Rh(1), and one Rh(2) atom.
