La4Ni3Pb4 crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are four inequivalent La sites. In the first La site, La is bonded in a 1-coordinate geometry to four Ni and five Pb atoms. There are a spread of La–Ni bond distances ranging from 2.78–3.79 Å. There are a spread of La–Pb bond distances ranging from 3.36–3.87 Å. In the second La site, La is bonded in a 1-coordinate geometry to four Ni and five Pb atoms. There are a spread of La–Ni bond distances ranging from 2.77–3.78 Å. There are a spread of La–Pb bond distances ranging from 3.36–3.87 Å. In the third La site, La is bonded in a 7-coordinate geometry to three Ni and seven Pb atoms. There are one shorter (3.02 Å) and two longer (3.03 Å) La–Ni bond lengths. There are a spread of La–Pb bond distances ranging from 3.29–4.07 Å. In the fourth La site, La is bonded in a 1-coordinate geometry to four Ni and five Pb atoms. There are a spread of La–Ni bond distances ranging from 2.78–3.79 Å. There are a spread of La–Pb bond distances ranging from 3.36–3.86 Å. There are three inequivalent Ni sites. In the first Ni site, Ni is bonded in a 9-coordinate geometry to five La, two Ni, and two Pb atoms. Both Ni–Ni bond lengths are 2.49 Å.
