(Pt3Os)2H2 crystallizes in the trigonal R3m space group. The structure consists of three 1333-74-0 atoms inside a Pt3Os framework. In the Pt3Os framework, Os(1) is bonded to six equivalent Pt(1) atoms to form corner-sharing OsPt6 octahedra. The corner-sharing octahedra are not tilted. There are three shorter (2.04 Å) and three longer (2.80 Å) Os(1)-Pt(1) bond lengths. Pt(1) is bonded in a distorted linear geometry to two equivalent Os(1) atoms.
