CaF2 crystallizes in the orthorhombic Pmc2_1 space group. Ca(1) is bonded in a 7-coordinate geometry to three equivalent F(2) and four equivalent F(1) atoms. There are two inequivalent F sites. In the first F site, F(1) is bonded in a rectangular see-saw-like geometry to four equivalent Ca(1) atoms. In the second F site, F(2) is bonded in a distorted T-shaped geometry to three equivalent Ca(1) atoms.
CaF2 crystallizes in the orthorhombic Pmc2_1 space group. Ca(1) is bonded in a 7-coordinate geometry to three equivalent F(2) and four equivalent F(1) atoms. There are a spread of Ca(1)-F(2) bond distances ranging from 2.22-2.31 Å. There are two shorter (2.42 Å) and two longer (2.44 Å) Ca(1)-F(1) bond lengths. There are two inequivalent F sites. In the first F site, F(1) is bonded in a rectangular see-saw-like geometry to four equivalent Ca(1) atoms. In the second F site, F(2) is bonded in a distorted T-shaped geometry to three equivalent Ca(1) atoms.
