Theoretical investigation of intramolecular magnetic interaction through an ethylenic coupler

Abstract

We show that an ethylenic coupler provides a very strong intramolecular magnetic interaction. A recently synthesized nitronyl nitroxide derivative, D-NIT2, is investigated by ab initio quantum chemical methods. The broken symmetry approach yields a coupling constant -541 K that is in good agreement with the observed value in solid state. © 2005 American Chemical Society.
