Topological degeneracy of magnetic orbitals in organic biradicals mediated by metal ions: triplet ground state in a titanium(IV) complex of Schiff base diquinone radical ligands
Abstract
A large intramolecular ferromagnetic interaction is observed in a titanium(IV) complex formed by two tridentate Schiff base semiquinoato radical ligands; this peculiar magnetic behaviour may be rationalised on the basis of the structural properties of the biradical compound.
