RhZnSi2 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one RhZnSi2 cluster. Rh(1) is bonded in a linear geometry to one Si(1) and one Si(2) atom. The Rh(1)-Si(1) bond length is 1.28 Å. The Rh(1)-Si(2) bond length is 1.28 Å. Zn(1) is bonded in a single-bond geometry to one Si(1) atom. The Zn(1)-Si(1) bond length is 1.02 Å. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded in a distorted water-like geometry to one Rh(1) and one Zn(1) atom. In the second Si site, Si(2) is bonded in a single-bond geometry to one Rh(1) atom.
