摘要：

The electronic spectrum and temperature dependence of the magnetic susceptibility of powdered KAlCuF6 is reported and shown to be consistent with the compressed tetragonal geometry of the CuF64- groups in this compound. Angular overlap bonding parameters are derived and used to estimate the magnetic coupling between the Cu2+ ions, which are linked in chains via the axial fluoride ligands. Good agreement is obtained with the observed exchange coupling constant J = -60 cm-1, and it is shown that this coupling is expected to be strongly dependent on the CuFCu bridging angle.
