MnCd2Pb crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two MnCd2Pb clusters. Mn(1) is bonded in a 2-coordinate geometry to one Cd(1) and one Pb(1) atom. The Mn(1)-Cd(1) bond length is 1.59 Å. The Mn(1)-Pb(1) bond length is 1.69 Å. There are two inequivalent Cd sites. In the first Cd site, Cd(1) is bonded in a distorted single-bond geometry to one Mn(1) and one Cd(2) atom. The Cd(1)-Cd(2) bond length is 1.90 Å. In the second Cd site, Cd(2) is bonded in a 2-coordinate geometry to one Cd(1) and one Pb(1) atom. The Cd(2)-Pb(1) bond length is 2.26 Å. Pb(1) is bonded in a 1-coordinate geometry to one Mn(1) and one Cd(2) atom.
