Abstract
Because the orbital angular momentum L z cf on the Fe(II) sites of the Fe(II)Fe(III) bimetallic oxalates is incompletely quenched by the crystal field, the spin-orbit coupling competes with the Jahn-Teller (JT) distortion energy. The value of L z cf depends on the cation between the bimetallic layers. When L z cf is sufficiently small, the open honeycomb lattice of each bimetallic layer is distorted at all temperatures below the JT transition temperature. But in a range of L z cf, the lattice is only distorted between lower and upper JT transition temperatures, T JT (l) and T JT (u). For some cations, L z cf may exceed the threshold required for the cancellation of the moments on the Fe(II) and Fe(III) sublattices at a temperature T comp below the transition temperature T c . Using elastic constants obtained from compounds that exhibit magnetic compensation, we find that T JT (l) always lies between T comp and T c and that T JT (u) always lies above T c .
