Ga Os Pt Pt
OsPt2Ga crystallizes in the monoclinic Cm space group. Os(1) is bonded in a 8-coordinate geometry to six equivalent Os(1), one Pt(1), and one Pt(2) atom. All Os(1)-Os(1) bond lengths are 2.81 Å. The Os(1)-Pt(1) bond length is 3.39 Å. The Os(1)-Pt(2) bond length is 3.39 Å. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a distorted water-like geometry to one Os(1) and two equivalent Ga(1) atoms. There is one shorter (1.58 Å) and one longer (1.99 Å) Pt(1)-Ga(1) bond length. In the second Pt site, Pt(2) is bonded in a distorted L-shaped geometry to one Os(1) and two equivalent Ga(1) atoms. There is one shorter (1.94 Å) and one longer (2.29 Å) Pt(2)-Ga(1) bond length. Ga(1) is bonded in a 4-coordinate geometry to two equivalent Pt(1) and two equivalent Pt(2) atoms.
