Cr Ni Pb Pb
CrNiPb2 is Indium-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one CrNiPb2 cluster. Cr(1) is bonded in a 2-coordinate geometry to one Ni(1) and one Pb(1) atom. The Cr(1)-Ni(1) bond length is 0.97 Å. The Cr(1)-Pb(1) bond length is 1.41 Å. Ni(1) is bonded in a 3-coordinate geometry to one Cr(1), one Pb(1), and one Pb(2) atom. The Ni(1)-Pb(1) bond length is 1.22 Å. The Ni(1)-Pb(2) bond length is 0.81 Å. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a 2-coordinate geometry to one Cr(1) and one Ni(1) atom. In the second Pb site, Pb(2) is bonded in a single-bond geometry to one Ni(1) atom.
