CeRhSi3 crystallizes in the tetragonal I4mm space group. Ce(1) is bonded in a 17-coordinate geometry to five equivalent Rh(1), four equivalent Si(1), and eight equivalent Si(2) atoms. Rh(1) is bonded in a 5-coordinate geometry to five equivalent Ce(1), one Si(1), and four equivalent Si(2) atoms. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded in a distorted single-bond geometry to four equivalent Ce(1), one Rh(1), and four equivalent Si(2) atoms. In the second Si site, Si(2) is bonded in a distorted bent 120 degrees geometry to four equivalent Ce(1), two equivalent Rh(1), and two equivalent Si(1) atoms.
CeRhSi3 crystallizes in the tetragonal I4mm space group. Ce(1) is bonded in a 17-coordinate geometry to five equivalent Rh(1), four equivalent Si(1), and eight equivalent Si(2) atoms. There are four shorter (3.36 Å) and one longer (3.37 Å) Ce(1)-Rh(1) bond length. All Ce(1)-Si(1) bond lengths are 3.10 Å. There are four shorter (3.12 Å) and four longer (3.36 Å) Ce(1)-Si(2) bond lengths. Rh(1) is bonded in a 5-coordinate geometry to five equivalent Ce(1), one Si(1), and four equivalent Si(2) atoms. The Rh(1)-Si(1) bond length is 2.37 Å. All Rh(1)-Si(2) bond lengths are 2.37 Å. There are two inequivalent Si sites.
