Solid CrF3 contains a Cr(III) ion surrounded by six F ions in an octahedral geometry, all at distances of 190 pm. However, MnF3 is in a distorted geometry, with Mn-F distances of 179, 191, and 209 pm. With comparing two octahedral complexes; suggest an explanation and also account for which type of tetragonal distortion should be expected for this structure.
