The structure described by CsNH4F2 crystallizes in the orthorhombic Pnma space group. Cs(1) is bonded in a 7-coordinate geometry to three equivalent F(2) and four equivalent F(1) atoms. N(1) is bonded in a tetrahedral geometry to one H(1), one H(3), and two equivalent H(2) atoms. There are three inequivalent H sites. In the first H site, H(1) is bonded in a distorted single-bond geometry to one N(1) and one F(1) atom. In the second H site, H(2) is bonded in a single-bond geometry to one N(1) atom. In the third H site, H(3) is bonded in a single-bond geometry to one N(1) atom. There are two inequivalent F sites. In the first F site, F(1) is bonded in a 1-coordinate geometry to four equivalent Cs(1) and one H(1) atom. In the second F site, F(2) is bonded in a 5-coordinate geometry to three equivalent Cs(1) atoms. is represented by the CIF card [CIF]
