The compound described by K2CrH2F8 crystallizes in the monoclinic P2_1/c space group. K(1) is bonded in a 9-coordinate geometry to two equivalent F(1), two equivalent F(3), two equivalent F(4), and three equivalent F(2) atoms. Cr(1) is bonded in an octahedral geometry to two equivalent F(1), two equivalent F(3), and two equivalent F(4) atoms. H(1) is bonded in a linear geometry to one F(1) and one F(2) atom. There are four inequivalent F sites. In the first F site, F(1) is bonded in a 2-coordinate geometry to two equivalent K(1), one Cr(1), and one H(1) atom. In the second F site, F(2) is bonded in a single-bond geometry to three equivalent K(1) and one H(1) atom. In the third F site, F(3) is bonded in a distorted single-bond geometry to two equivalent K(1) and one Cr(1) atom. In the fourth F site, F(4) is bonded in a distorted single-bond geometry to two equivalent K(1) and one Cr(1) atom. is represented by the CIF card [CIF]
