Os2GaPb crystallizes in the triclinic P1 space group. There are two inequivalent Os sites. In the first Os site, Os(1) is bonded in a distorted linear geometry to two equivalent Os(2), two equivalent Ga(1), and two equivalent Pb(1) atoms. There is one shorter (2.58 Å) and one longer (2.85 Å) Os(1)-Os(2) bond length. There is one shorter (1.48 Å) and one longer (1.54 Å) Os(1)-Ga(1) bond length. There is one shorter (2.42 Å) and one longer (2.98 Å) Os(1)-Pb(1) bond length. In the second Os site, Os(2) is bonded in a 8-coordinate geometry to two equivalent Os(1), two equivalent Os(2), two equivalent Ga(1), and two equivalent Pb(1) atoms. Both Os(2)-Os(2) bond lengths are 3.01 Å. There is one shorter (2.62 Å) and one longer (2.79 Å) Os(2)-Ga(1) bond length. There is one shorter (2.51 Å) and one longer (2.54 Å) Os(2)-Pb(1) bond length. Ga(1) is bonded in a distorted linear geometry to two equivalent Os(1), two equivalent Os(2), and two equivalent Pb(1) atoms. There is one shorter (2.52 Å) and one longer (2.88 Å) Ga(1)-Pb(1) bond length. Pb(1) is bonded in a 8-coordinate geometry to two equivalent Os(1), two equivalent Os(2), two equivalent Ga(1), and two equivalent Pb(1) atoms. Both Pb(1)-Pb(1) bond lengths are 3.01 Å.
