La Si Si Rh
LaRhSi2 crystallizes in the triclinic P1 space group. La(1) is bonded in a 1-coordinate geometry to one Si(1) and two equivalent Si(2) atoms. The La(1)-Si(1) bond length is 1.64 Å. There is one shorter (2.53 Å) and one longer (3.55 Å) La(1)-Si(2) bond length. Rh(1) is bonded in a distorted single-bond geometry to one Si(2) and two equivalent Si(1) atoms. The Rh(1)-Si(2) bond length is 2.50 Å. There is one shorter (0.80 Å) and one longer (2.29 Å) Rh(1)-Si(1) bond length. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded in a 3-coordinate geometry to one La(1) and two equivalent Rh(1) atoms. In the second Si site, Si(2) is bonded in a 3-coordinate geometry to two equivalent La(1) and one Rh(1) atom.
