The compound described by FeNiAg2F7 crystallizes in the orthorhombic Imma space group. Fe(1) is bonded to two equivalent F(3) and four equivalent F(2) atoms to form FeF6 octahedra that share corners with two equivalent Fe(1)F6 octahedra and corners with four equivalent Ni(1)F6 octahedra. The corner-sharing octahedral tilt angles range from 38-40°. Ni(1) is bonded to two equivalent F(1) and four equivalent F(2) atoms to form NiF6 octahedra that share corners with four equivalent Fe(1)F6 octahedra. The corner-sharing octahedral tilt angles are 38°. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a distorted linear geometry to two equivalent F(1) and four equivalent F(2) atoms. In the second Ag site, Ag(2) is bonded in a square co-planar geometry to four equivalent F(1) atoms. There are three inequivalent F sites. In the first F site, F(1) is bonded to one Ni(1), one Ag(1), and two equivalent Ag(2) atoms to form a mixture of distorted edge and corner-sharing FNiAg3 tetrahedra. In the second F site, F(2) is bonded in a distorted bent 150 degrees geometry to one Fe(1), one Ni(1), and one Ag(1) atom. In the third F site, F(3) is bonded in a bent 150 degrees geometry to two equivalent Fe(1) atoms. is represented by the CIF card [CIF]
