Nb Co Co Pb
NbCo2Pb crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one NbCo2Pb cluster. Nb(1) is bonded in a distorted L-shaped geometry to one Co(2) and one Pb(1) atom. The Nb(1)-Co(2) bond length is 0.40 Å. The Nb(1)-Pb(1) bond length is 0.40 Å. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a distorted single-bond geometry to one Co(2) and one Pb(1) atom. The Co(1)-Co(2) bond length is 0.96 Å. The Co(1)-Pb(1) bond length is 0.96 Å. In the second Co site, Co(2) is bonded in a 2-coordinate geometry to one Nb(1), one Co(1), and one Pb(1) atom. The Co(2)-Pb(1) bond length is 0.52 Å. Pb(1) is bonded in a distorted single-bond geometry to one Nb(1), one Co(1), and one Co(2) atom.
