The material described by KVNiOF6 crystallizes in the orthorhombic Imma space group. K(1) is bonded to two equivalent O(1), two equivalent F(1), and four equivalent F(3) atoms to form KO2F6 hexagonal bipyramids that share edges with two equivalent K(1)O2F6 hexagonal bipyramids, edges with two equivalent V(1)F6 octahedra, and edges with four equivalent Ni(1)F6 octahedra. V(1) is bonded to two equivalent F(2) and four equivalent F(3) atoms to form VF6 octahedra that share corners with two equivalent V(1)F6 octahedra, corners with four equivalent Ni(1)F6 octahedra, and edges with two equivalent K(1)O2F6 hexagonal bipyramids. The corner-sharing octahedral tilt angles range from 35-39°. Ni(1) is bonded to two equivalent F(1) and four equivalent F(3) atoms to form NiF6 octahedra that share corners with two equivalent Ni(1)F6 octahedra, corners with four equivalent V(1)F6 octahedra, and edges with four equivalent K(1)O2F6 hexagonal bipyramids. The corner-sharing octahedral tilt angles range from 39-42°. O(1) is bonded in an L-shaped geometry to two equivalent K(1) atoms. There are three inequivalent F sites. In the first F site, F(1) is bonded in a 4-coordinate geometry to two equivalent K(1) and two equivalent Ni(1) atoms. In the second F site, F(2) is bonded in a bent 150 degrees geometry to two equivalent V(1) atoms. In the third F site, F(3) is bonded in a 3-coordinate geometry to one K(1), one V(1), and one Ni(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
