La5MnPb3 crystallizes in the hexagonal P6_3/mcm space group. There are two inequivalent La sites. In the first La site, La(1) is bonded to two equivalent Mn(1) and five equivalent Pb(1) atoms to form a mixture of distorted edge, corner, and face-sharing LaMn2Pb5 pentagonal bipyramids. In the second La site, La(2) is bonded in a 6-coordinate geometry to six equivalent Pb(1) atoms. Mn(1) is bonded to six equivalent La(1) atoms to form face-sharing MnLa6 octahedra. Pb(1) is bonded in a 9-coordinate geometry to four equivalent La(2) and five equivalent La(1) atoms.

In the first La site, La(1) is bonded to two equivalent Mn(1) and five equivalent Pb(1) atoms to form a mixture of distorted edge, corner, and face-sharing LaMn2Pb5 pentagonal bipyramids. Both La(1)-Mn(1) bond lengths are 3.02 Å. There are a spread of La(1)-Pb(1) bond distances ranging from 3.38-3.80 Å. In the second La site, La(2) is bonded in a 6-coordinate geometry to six equivalent Pb(1) atoms. All La(2)-Pb(1) bond lengths are 3.49 Å. Mn(1) is bonded to six equivalent La(1) atoms to form face-sharing MnLa6 octahedra. Pb(1) is bonded in a 9-coordinate geometry to four equivalent La(2) and five equivalent La(1) atoms.
