K Sr Sr Rh
KSr2Rh is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two KSr2Rh clusters. K(1) is bonded in a 3-coordinate geometry to two equivalent Sr(1) and one Rh(1) atom. Both K(1)-Sr(1) bond lengths are 2.08 Å. The K(1)-Rh(1) bond length is 2.23 Å. Sr(1) is bonded in a 1-coordinate geometry to one K(1) and one Rh(1) atom. The Sr(1)-Rh(1) bond length is 2.08 Å. Rh(1) is bonded in a 3-coordinate geometry to one K(1) and two equivalent Sr(1) atoms.
