NaMnCrF6 is Hydrophilite-derived structured and crystallizes in the trigonal P321 space group. Na(1) is bonded to two equivalent F(1), two equivalent F(2), and two equivalent F(3) atoms to form NaF6 octahedra that share corners with four equivalent Cr(1)F6 octahedra, corners with six equivalent Mn(1)F6 octahedra, and  an edgeedge with one Cr(2)F6 octahedra. The corner-sharing octahedral tilt angles range from 50-56°. There are two inequivalent Cr sites. In the first Cr site, Cr(1) is bonded to three equivalent F(1) and three equivalent F(2) atoms to form CrF6 octahedra that share corners with six equivalent Na(1)F6 octahedra and edges with three equivalent Mn(1)F6 octahedra. The corner-sharing octahedral tilt angles range from 50-52°. In the second Cr site, Cr(2) is bonded to six equivalent F(3) atoms to form CrF6 octahedra that share corners with six equivalent Mn(1)F6 octahedra and edges with three equivalent Na(1)F6 octahedra. The corner-sharing octahedral tilt angles are 47°. Mn(1) is bonded to two equivalent F(1), two equivalent F(2), and two equivalent F(3) atoms to form MnF6 octahedra that share corners with two equivalent Cr(2)F6 octahedra, corners with six equivalent Na(1)F6 octahedra, and edges with two equivalent Cr(1)F6 octahedra. The corner-sharing octahedral tilt angles range from 47-56°. There are three inequivalent F sites. In the first F site, F(1) is bonded in a trigonal planar geometry to one Na(1), one Cr(1), and one Mn(1) atom.
