NbOsGaPb crystallizes in the trigonal R3m space group. Nb(1) is bonded in a single-bond geometry to four equivalent Os(1), one Ga(1), and three equivalent Pb(1) atoms. There are three shorter (2.73 Å) and one longer (3.83 Å) Nb(1)-Os(1) bond length. The Nb(1)-Ga(1) bond length is 0.09 Å. All Nb(1)-Pb(1) bond lengths are 2.73 Å. Os(1) is bonded in a 10-coordinate geometry to four equivalent Nb(1), three equivalent Ga(1), and three equivalent Pb(1) atoms. All Os(1)-Ga(1) bond lengths are 2.73 Å. All Os(1)-Pb(1) bond lengths are 2.73 Å. Ga(1) is bonded in a single-bond geometry to one Nb(1), three equivalent Os(1), and three equivalent Pb(1) atoms. All Ga(1)-Pb(1) bond lengths are 2.73 Å. Pb(1) is bonded in a distorted q6 geometry to three equivalent Nb(1), three equivalent Os(1), and three equivalent Ga(1) atoms.
