CrNiAg2F7 crystallizes in the orthorhombic Imma space group. Cr(1) is bonded to two equivalent F(3) and four equivalent F(2) atoms to form CrF6 octahedra that share corners with two equivalent Cr(1)F6 octahedra, corners with four equivalent Ni(1)F6 octahedra, and corners with four equivalent Ag(1)F6 octahedra. The corner-sharing octahedral tilt angles range from 38-71°. Ni(1) is bonded to two equivalent F(1) and four equivalent F(2) atoms to form NiF6 octahedra that share corners with two equivalent Ag(1)F6 octahedra, corners with four equivalent Cr(1)F6 octahedra, and edges with two equivalent Ag(1)F6 octahedra. The corner-sharing octahedral tilt angles range from 38-55°. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded to two equivalent F(1) and four equivalent F(2) atoms to form distorted AgF6 octahedra that share corners with two equivalent Ni(1)F6 octahedra, corners with four equivalent Cr(1)F6 octahedra, and edges with two equivalent Ni(1)F6 octahedra. The corner-sharing octahedral tilt angles range from 55-71°. 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 corner and edge-sharing FNiAg3 tetrahedra. In the second F site, F(2) is bonded in a distorted bent 150 degrees geometry to one Cr(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 Cr(1) atoms.
