K3LiPb4 crystallizes in the orthorhombic Cmcm space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a distorted bent 150 degrees geometry to six equivalent Pb(2) atoms. In the second K site, K(2) is bonded in a 7-coordinate geometry to three equivalent Pb(2) and four equivalent Pb(1) atoms. Li(1) is bonded in a distorted hexagonal planar geometry to two equivalent Pb(2) and four equivalent Pb(1) atoms. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a 6-coordinate geometry to four equivalent K(2), two equivalent Li(1), and two equivalent Pb(2) atoms. In the second Pb site, Pb(2) is bonded in a 10-coordinate geometry to three equivalent K(1), three equivalent K(2), one Li(1), one Pb(2), and two equivalent Pb(1) atoms.
K3LiPb4 crystallizes in the orthorhombic Cmcm space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a distorted bent 150 degrees geometry to six equivalent Pb(2) atoms. There are two shorter (3.77 Å) and four longer (4.17 Å) K(1)-Pb(2) bond lengths. In the second K site, K(2) is bonded in a 7-coordinate geometry to three equivalent Pb(2) and four equivalent Pb(1) atoms. There is one shorter (3.52 Å) and two longer (3.97 Å) K(2)-Pb(2) bond lengths. There are two shorter (3.73 Å) and two longer (3.81 Å) K(2)-Pb(1) bond lengths. Li(1) is bonded in a distorted hexagonal planar geometry to two equivalent Pb(2) and four equivalent Pb(1) atoms. Both Li(1)-Pb(2) bond lengths are 2.96 Å. All Li(1)-Pb(1) bond lengths are 3.10 Å. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a 6-coordinate geometry to four equivalent K(2), two equivalent Li(1), and two equivalent Pb(2) atoms.
