(SrAlOF4)2H2 crystallizes in the monoclinic P2_1/c space group. The structure consists of four 1333-74-0 atoms inside a SrAlOF4 framework. In the SrAlOF4 framework, Sr(1) is bonded in a 6-coordinate geometry to one F(1), one F(3), two equivalent F(2), and two equivalent F(4) atoms. Al(1) is bonded to two equivalent O(1), one F(1), one F(2), one F(3), and one F(4) atom to form edge-sharing AlO2F4 octahedra. O(1) is bonded in a bent 120 degrees geometry to two equivalent Al(1) atoms. There are four inequivalent F sites. In the first F site, F(1) is bonded in a distorted linear geometry to one Sr(1) and one Al(1) atom. In the second F site, F(2) is bonded in a 3-coordinate geometry to two equivalent Sr(1) and one Al(1) atom. In the third F site, F(3) is bonded in a bent 120 degrees geometry to one Sr(1) and one Al(1) atom. In the fourth F site, F(4) is bonded in a distorted trigonal planar geometry to two equivalent Sr(1) and one Al(1) atom.
