Os2Pt crystallizes in the trigonal R3m space group. There are six inequivalent Os sites. In the first Os site, Os(1) is bonded in a 5-coordinate geometry to two equivalent Os(1), one Pt(1), and two equivalent Pt(4) atoms. Both Os(1)-Os(1) bond lengths are 1.16 Å. The Os(1)-Pt(1) bond length is 1.35 Å. Both Os(1)-Pt(4) bond lengths are 2.74 Å. In the second Os site, Os(2) is bonded in a single-bond geometry to one Pt(1) atom. The Os(2)-Pt(1) bond length is 0.72 Å. In the third Os site, Os(3) is bonded in a 4-coordinate geometry to two equivalent Os(3), two equivalent Os(4), and one Pt(3) atom. Both Os(3)-Os(3) bond lengths are 0.34 Å. Both Os(3)-Os(4) bond lengths are 0.59 Å. The Os(3)-Pt(3) bond length is 3.25 Å. In the fourth Os site, Os(4) is bonded in a 2-coordinate geometry to two equivalent Os(3), two equivalent Os(4), one Pt(2), and two equivalent Pt(4) atoms. Both Os(4)-Os(4) bond lengths are 0.34 Å. The Os(4)-Pt(2) bond length is 2.02 Å. Both Os(4)-Pt(4) bond lengths are 1.81 Å. In the fifth Os site, Os(5) is bonded in a 4-coordinate geometry to two equivalent Os(5) and two equivalent Os(6) atoms. Both Os(5)-Os(5) bond lengths are 0.34 Å. Both Os(5)-Os(6) bond lengths are 0.59 Å. In the sixth Os site, Os(6) is bonded in a 2-coordinate geometry to two equivalent Os(5), two equivalent Os(6), one Pt(4), and two equivalent Pt(2) atoms. Both Os(6)-Os(6) bond lengths are 0.34 Å. The Os(6)-Pt(4) bond length is 2.02 Å. Both Os(6)-Pt(2) bond lengths are 1.81 Å. There are four inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a 4-coordinate geometry to one Os(2) and three equivalent Os(1) atoms.
