Co Rh Pb Pb
RhCoPb2 crystallizes in the monoclinic Pm space group. Rh(1) is bonded in a distorted single-bond geometry to one Co(1) and two equivalent Pb(1) atoms. The Rh(1)-Co(1) bond length is 1.52 Å. Both Rh(1)-Pb(1) bond lengths are 2.47 Å. Co(1) is bonded in a 1-coordinate geometry to one Rh(1) and four equivalent Pb(1) atoms. There are two shorter (2.47 Å) and two longer (3.00 Å) Co(1)-Pb(1) bond lengths. Pb(1) is bonded in a 4-coordinate geometry to one Rh(1), two equivalent Co(1), and one Pb(1) atom. The Pb(1)-Pb(1) bond length is 1.86 Å.
