The compound described by AgNbF6 crystallizes in the tetragonal P4_2/mcm space group. Nb(1) is bonded in an octahedral geometry to two equivalent F(2) and four equivalent F(1) atoms. Ag(1) is bonded in a 4-coordinate geometry to four equivalent F(1) atoms. There are two inequivalent F sites. In the first F site, F(2) is bonded in a single-bond geometry to one Nb(1) atom. In the second F site, F(1) is bonded in a distorted bent 150 degrees geometry to one Nb(1) and one Ag(1) atom. is represented by the CIF card [CIF]
