La4Ni3Pb4 crystallizes in the trigonal R3 space group. There are two inequivalent La sites. In the first La site, La(1) is bonded in a 1-coordinate geometry to four equivalent Ni(1), one Pb(2), and four equivalent Pb(1) atoms. In the second La site, La(2) is bonded in a 7-coordinate geometry to three equivalent Ni(1), one Pb(2), and six equivalent Pb(1) atoms. Ni(1) is bonded in a 9-coordinate geometry to one La(2), four equivalent La(1), two equivalent Ni(1), and two equivalent Pb(1) atoms. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a 9-coordinate geometry to two equivalent La(2), four equivalent La(1), two equivalent Ni(1), and one Pb(2) atom. In the second Pb site, Pb(2) is bonded in a 4-coordinate geometry to one La(2), three equivalent La(1), and three equivalent Pb(1) atoms.
