K Si Rh Rh
KRh2Si crystallizes in the monoclinic Pm space group. The structure is zero-dimensional and consists of one KRh2Si cluster. K(1) is bonded in a single-bond geometry to one Rh(2) and one Si(1) atom. The K(1)-Rh(2) bond length is 2.47 Å. The K(1)-Si(1) bond length is 0.83 Å. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a single-bond geometry to one Si(1) atom. The Rh(1)-Si(1) bond length is 1.64 Å. In the second Rh site, Rh(2) is bonded in a single-bond geometry to one K(1) atom. Si(1) is bonded in a distorted single-bond geometry to one K(1) and one Rh(1) atom.
