14. In trivalent manganese compounds, a tetragonal distortion occurs in the octahedral coordination of the Mn3+ cf ions due to the Jahn-Teller stabilisation of the electronic structure, which produces two axial Mn-O bonds of ca. 2. 3 A and four equatorial bonds of ca. 1. 9 A. In LiMnU2 materials, the crystal structures adapt to this localised distortion through a cooperative effect where all the long bonds are orientated along the same crystal direction.
