The compound described by LiAl2Pb2H4(O2F3)2 crystallizes in the triclinic P-1 space group. Li(1) is bonded in a square co-planar geometry to two equivalent F(1) and 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 4-coordinate geometry to one O(1), two equivalent O(2), and one F(2) 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) and one F(1) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to two equivalent Al(1), one Pb(1), and one H(1) atom. In the second O site, O(2) is bonded in a 1-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 3-coordinate geometry to one Li(1), one Al(1), and one H(2) atom. In the second F site, F(2) is bonded in a distorted single-bond geometry to one Al(1) and one Pb(1) atom. In the third F site, F(3) is bonded in an L-shaped geometry to one Li(1) and one Al(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
