For dimeric copper(II) carboxylates, the most important factor determi
ning the strength of the spin superexchange interactions is the electr
onic structure of the carboxylato bridge. It also has been revealed th
at the trigonal bipyramidal deformation of the coordination geometry a
round the copper atoms, and the bending of the carboxylato bridge decr
ease the antiferromagnetic interactions.
