Cr Cr Si Rh
Cr2RhSi crystallizes in the monoclinic Cm space group. There are two inequivalent Cr sites. In the first Cr site, Cr(1) is bonded in a single-bond geometry to one Rh(1) and one Si(1) atom. The Cr(1)-Rh(1) bond length is 1.47 Å. The Cr(1)-Si(1) bond length is 2.47 Å. In the second Cr site, Cr(2) is bonded in a single-bond geometry to one Rh(1) and one Si(1) atom. The Cr(2)-Rh(1) bond length is 1.47 Å. The Cr(2)-Si(1) bond length is 3.04 Å. Rh(1) is bonded in a linear geometry to one Cr(1) and one Cr(2) atom. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded in a 8-coordinate geometry to one Cr(1); one Cr(2); and six Si(1,1) atoms. All Si(1)-Si(1,1) bond lengths are 2.64 Å. In the second Si site, Si(1) is bonded in a 8-coordinate geometry to one Cr(1); one Cr(2); and six Si(1,1) atoms. The Si(1)-Cr(1) bond length is 2.47 Å. The Si(1)-Cr(2) bond length is 3.04 Å. Both Si(1)-Si(1) bond lengths are 2.64 Å.
