CaAl2Pb2H4(O2F3)2 crystallizes in the triclinic P-1 space group. Ca(1) is bonded in a 4-coordinate 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 3-coordinate geometry to 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 distorted trigonal planar geometry to two equivalent Al(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 Ca(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 a water-like geometry to one Ca(1) and one Al(1) atom.
