Abstract A difference in a magnetic behavior of two different types of pyrazole-bridged dinuclear Cu(II) complexes are explained by a concept of the orbital complementarity and the density functional theory (DFT) calculations. The DFT calculations reproduce the experimental J values, and the estimated orbital overlap between Cu(II) ions are quite small, indicating that the spins are localized on the Cu(II) ions. The quasi-degenerate frontier orbital energies indicate that the ferromagnetic interaction of the acetate complex can be explained by the orbital complementarity.
