LiAl2Pb2H4(O2F3)2 crystallizes in the triclinic P-1 space group. Li(1) is bonded in a distorted linear geometry to two equivalent F(3) atoms. Al(1) is bonded to one O(2), two equivalent O(1), one F(1), one F(2), and one F(3) atom to form edge-sharing AlO3F3 octahedra. Pb(1) is bonded in a distorted pentagonal planar geometry to two equivalent O(2), one F(1), one F(2), and one F(3) atom. There are two inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one O(1) atom. In the second H site, H(2) is bonded in a single-bond geometry to one O(2) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 1-coordinate geometry to two equivalent Al(1) and one H(1) atom. In the second O site, O(2) is bonded in a 2-coordinate geometry to one Al(1), two equivalent Pb(1), and one H(2) atom. There are three inequivalent F sites. In the first F site, F(1) is bonded in a distorted single-bond geometry to one Al(1) and one Pb(1) atom.
