Magnetic exchange interaction in the Ti2Cl 3–9 anion

Abstract

The general theory of magnetic exchange interaction between two atoms with orbitally degenerate wavefunctions has been applied to the interaction of two Ti(III) ions in the Ti₂Cl^3–₉ anion. The treatment was numerical rather than algebraic so the magnitudes of the various perturbations could be varied over a wide range. It was possible to obtain excellent agreement with the experimental magnetic susceptibility for the Ti₂Cl^3–₉ anion over the temperature range 90 to 300 K.
