La5AgPb3 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 Ag(1) and five equivalent Pb(1) atoms to form a mixture of distorted face, corner, and edge-sharing LaAg2Pb5 pentagonal bipyramids. In the second La site, La(2) is bonded in a 6-coordinate geometry to six equivalent Pb(1) atoms. Ag(1) is bonded to six equivalent La(1) atoms to form face-sharing AgLa6 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 Ag(1) and five equivalent Pb(1) atoms to form a mixture of distorted face, corner, and edge-sharing LaAg2Pb5 pentagonal bipyramids. Both La(1)-Ag(1) bond lengths are 3.21 Å. There are a spread of La(1)-Pb(1) bond distances ranging from 3.32-3.64 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 3.55 Å. Ag(1) is bonded to six equivalent La(1) atoms to form face-sharing AgLa6 octahedra. Pb(1) is bonded in a 9-coordinate geometry to four equivalent La(2) and five equivalent La(1) atoms.
