GdNiPb crystallizes in the orthorhombic Pmc2_1 space group. There are two inequivalent Gd sites. In the first Gd site, Gd(1) is bonded in a 12-coordinate geometry to two equivalent Ni(1), four equivalent Ni(2), two equivalent Pb(1), and four equivalent Pb(2) atoms. In the second Gd site, Gd(2) is bonded in a 12-coordinate geometry to two equivalent Ni(2), four equivalent Ni(1), two equivalent Pb(2), and four equivalent Pb(1) atoms. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 10-coordinate geometry to two equivalent Gd(1), four equivalent Gd(2), two equivalent Pb(1), and two equivalent Pb(2) atoms. In the second Ni site, Ni(2) is bonded in a 10-coordinate geometry to two equivalent Gd(2), four equivalent Gd(1), two equivalent Pb(1), and two equivalent Pb(2) atoms. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a 10-coordinate geometry to two equivalent Gd(1), four equivalent Gd(2), two equivalent Ni(1), and two equivalent Ni(2) atoms. In the second Pb site, Pb(2) is bonded in a 10-coordinate geometry to two equivalent Gd(2), four equivalent Gd(1), two equivalent Ni(1), and two equivalent Ni(2) atoms.
