CsC(OF)2 crystallizes in the orthorhombic Pnma space group. Cs(1) is bonded in a 10-coordinate geometry to six equivalent O(1), one F(1), and three equivalent F(2) atoms. C(1) is bonded in a tetrahedral geometry to two equivalent O(1), one F(1), and one F(2) atom. O(1) is bonded in a single-bond geometry to three equivalent Cs(1) and one C(1) atom. There are two inequivalent F sites. In the first F site, F(1) is bonded in a single-bond geometry to one Cs(1) and one C(1) atom. In the second F site, F(2) is bonded in a single-bond geometry to three equivalent Cs(1) and one C(1) atom.
CsC(OF)2 crystallizes in the orthorhombic Pnma space group. Cs(1) is bonded in a 10-coordinate geometry to six equivalent O(1), one F(1), and three equivalent F(2) atoms. There are a spread of Cs(1)-O(1) bond distances ranging from 3.16-3.25 Å. The Cs(1)-F(1) bond length is 3.26 Å. There is one shorter (3.17 Å) and two longer (3.40 Å) Cs(1)-F(2) bond lengths. C(1) is bonded in a tetrahedral geometry to two equivalent O(1), one F(1), and one F(2) atom. Both C(1)-O(1) bond lengths are 1.31 Å. The C(1)-F(1) bond length is 1.45 Å. The C(1)-F(2) bond length is 1.47 Å. O(1) is bonded in a single-bond geometry to three equivalent Cs(1) and one C(1) atom. There are two inequivalent F sites. In the first F site, F(1) is bonded in a single-bond geometry to one Cs(1) and one C(1) atom. In the second F site, F(2) is bonded in a single-bond geometry to three equivalent Cs(1) and one C(1) atom.
