RbNiCrF6 crystallizes in the orthorhombic Imma space group. Rb(1) is bonded to one F(1), one F(2), and four equivalent F(3) atoms to form RbF6 octahedra that share corners with six equivalent Cr(1)F6 octahedra and corners with six equivalent Ni(1)F6 octahedra. The corner-sharing octahedral tilt angles range from 67-69°. Cr(1) is bonded to two equivalent F(1) and four equivalent F(3) 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 six equivalent Rb(1)F6 octahedra. The corner-sharing octahedral tilt angles range from 42-69°. Ni(1) is bonded to two equivalent F(2) and four equivalent F(3) atoms to form NiF6 octahedra that share corners with two equivalent Ni(1)F6 octahedra, corners with four equivalent Cr(1)F6 octahedra, and corners with six equivalent Rb(1)F6 octahedra. The corner-sharing octahedral tilt angles range from 44-69°. There are three inequivalent F sites. In the first F site, F(1) is bonded in a distorted bent 150 degrees geometry to one Rb(1) and two equivalent Cr(1) atoms. In the second F site, F(2) is bonded in a distorted trigonal planar geometry to one Rb(1) and two equivalent Ni(1) atoms. In the third F site, F(3) is bonded in a 2-coordinate geometry to one Rb(1), one Cr(1), and one Ni(1) atom.
