Cs2CrH4F10 crystallizes in the monoclinic P2_1/c space group. Cs(1) is bonded in a 12-coordinate geometry to one F(1), two equivalent F(3), three equivalent F(2), three equivalent F(4), and three equivalent F(5) atoms. Cr(1) is bonded in an octahedral geometry to two equivalent F(1), two equivalent F(2), and two equivalent F(3) atoms. There are two inequivalent H sites. In the first H site, H(1) is bonded in a linear geometry to one F(3) and one F(4) atom. In the second H site, H(2) is bonded in a linear geometry to one F(1) and one F(5) atom. There are five inequivalent F sites. In the first F site, F(1) is bonded in a distorted bent 150 degrees geometry to one Cs(1), one Cr(1), and one H(2) atom. In the second F site, F(2) is bonded in a single-bond geometry to three equivalent Cs(1) and one Cr(1) atom. In the third F site, F(3) is bonded in a bent 120 degrees geometry to two equivalent Cs(1), one Cr(1), and one H(1) atom.
