The compound described by Na2CrH2F8 crystallizes in the monoclinic C2/m space group. Na(1) is bonded in a 8-coordinate geometry to two equivalent F(2), two equivalent F(3), and four equivalent F(1) atoms. Cr(1) is bonded in an octahedral geometry to two equivalent F(2) and four equivalent F(1) atoms. H(1) is bonded in a distorted linear geometry to one F(2) and one F(3) atom. There are three inequivalent F sites. In the first F site, F(1) is bonded in a 3-coordinate geometry to two equivalent Na(1) and one Cr(1) atom. In the second F site, F(2) is bonded in a 4-coordinate geometry to two equivalent Na(1), one Cr(1), and one H(1) atom. In the third F site, F(3) is bonded in a single-bond geometry to two equivalent Na(1) and one H(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
