Nb Rh Rh Pb
NbRh2Pb crystallizes in the monoclinic Pm space group. The structure is zero-dimensional and consists of one NbRh2Pb cluster. Nb(1) is bonded in a distorted single-bond geometry to one Rh(1) atom. The Nb(1)-Rh(1) bond length is 1.67 Å. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a 2-coordinate geometry to one Nb(1) and one Pb(1) atom. The Rh(1)-Pb(1) bond length is 1.57 Å. In the second Rh site, Rh(2) is bonded in a distorted single-bond geometry to one Pb(1) atom. The Rh(2)-Pb(1) bond length is 1.57 Å. Pb(1) is bonded in a distorted bent 120 degrees geometry to one Rh(1) and one Rh(2) atom.
