Sr Rh Rh
SrRh2 is Hg_xSn structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one SrRh2 cluster. Sr(1) is bonded in a distorted water-like geometry to one Rh(1) and one Rh(2) atom. The Sr(1)-Rh(1) bond length is 1.65 Å. The Sr(1)-Rh(2) bond length is 1.93 Å. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a distorted single-bond geometry to one Sr(1) atom. In the second Rh site, Rh(2) is bonded in a single-bond geometry to one Sr(1) atom.
