Electron paramagnetic resonance and density-functional theory studies of Cu(II)-bis(oxamato) complexes

A study was conducted to determine the influence of electronic and structural variations induced by varying the N,N-bridge on the magnetic properties of Cu(II)-bis(oxamato) complexes. The spin population for the monomeric building blocks was found to be correlated to the exchange interaction of the corresponding trinuclear complexes on their geometry.
