Ba Pt Pt Rh
BaRhPt2 crystallizes in the monoclinic Cm space group. Ba(1) is bonded in a 2-coordinate geometry to one Rh(1) and three equivalent Pt(2) atoms. The Ba(1)-Rh(1) bond length is 2.28 Å. There is one shorter (2.99 Å) and two longer (3.66 Å) Ba(1)-Pt(2) bond lengths. Rh(1) is bonded in a distorted water-like geometry to one Ba(1) and one Pt(1) atom. The Rh(1)-Pt(1) bond length is 1.51 Å. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a 1-coordinate geometry to one Rh(1) and one Pt(2) atom. The Pt(1)-Pt(2) bond length is 2.17 Å. In the second Pt site, Pt(2) is bonded in a 4-coordinate geometry to three equivalent Ba(1) and one Pt(1) atom.
