Abstract

© 2015 The Royal Society of Chemistry. The synthesis, structural, electronic and magnetic characterization of five dinuclear Co(ii) azacryptand compounds (1-5) bridged through different ions are reported. The magnetic exchange interactions, 2J values, obtained from theoretical computations show that the variation of the intermetallic angles and distances lead to antiferromagnetic behaviours. Magneto-structural correlations show a trend, where the angles Co(ii)-bridge-Co(ii) closer to 180° favour an increase in the superexchange pathway leading to higher AF interaction values.
