✦ Synopsis

were analyzed by examining the structures of their spin monomers and calculating the energy di4erences e in the spin levels of their spin dimers. The trends in the observed J parameters are well explained in terms of the e values obtained from extended HuK ckel molecular orbital calculations. The e value of a spin dimer is related only to the antiferromagnetic component of its J, but the spin dimer analysis based on e allows one to correlate the nature of the magnetic interaction with the structure of the spin dimer.
