The material described by AgAlF4 crystallizes in the orthorhombic P2_12_12 space group. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a 4-coordinate geometry to two equivalent F(2) and two equivalent F(4) atoms. In the second Ag site, Ag(2) is bonded in a 4-coordinate geometry to two equivalent F(2) and two equivalent F(4) atoms. Al(1) is bonded to one F(2), one F(4), two equivalent F(1), and two equivalent F(3) atoms to form corner-sharing AlF6 octahedra. The corner-sharing octahedral tilt angles range from 26-28°. There are four inequivalent F sites. In the first F site, F(1) is bonded in a bent 150 degrees geometry to two equivalent Al(1) atoms. In the second F site, F(2) is bonded in a distorted single-bond geometry to one Ag(1), one Ag(2), and one Al(1) atom. In the third F site, F(3) is bonded in a bent 150 degrees geometry to two equivalent Al(1) atoms. In the fourth F site, F(4) is bonded in a distorted single-bond geometry to one Ag(1), one Ag(2), and one Al(1) atom. is represented by the CIF file [CIF]
