Os3Cl crystallizes in the trigonal R3 space group. There are two inequivalent Os sites. In the first Os site, Os(1) is bonded in a 6-coordinate geometry to two equivalent Os(2), two equivalent Cl(1), and two equivalent Cl(2) atoms. There is one shorter (2.49 Å) and one longer (2.51 Å) Os(1)-Os(2) bond length. There is one shorter (2.79 Å) and one longer (2.80 Å) Os(1)-Cl(1) bond length. There is one shorter (2.79 Å) and one longer (2.80 Å) Os(1)-Cl(2) bond length. In the second Os site, Os(2) is bonded in a 6-coordinate geometry to two equivalent Os(1), two equivalent Cl(1), and two equivalent Cl(2) atoms. There is one shorter (2.79 Å) and one longer (2.80 Å) Os(2)-Cl(1) bond length. There is one shorter (2.79 Å) and one longer (2.80 Å) Os(2)-Cl(2) bond length. There are two inequivalent Cl sites. In the first Cl site, Cl(1) is bonded to six equivalent Os(1) and six equivalent Os(2) atoms to form a mixture of edge and face-sharing ClOs12 cuboctahedra. In the second Cl site, Cl(2) is bonded to six equivalent Os(1) and six equivalent Os(2) atoms to form a mixture of edge and face-sharing ClOs12 cuboctahedra.
