2003 journal article

Trends in exchange coupling for trimethylenemethane-type bis(semiquinone) biradicals and correlation of magnetic exchange with mixed valency for cross-conjugated systems

JOURNAL OF THE AMERICAN CHEMICAL SOCIETY, 125(38), 11761–11771.

TL;DR: The results suggest that delocalization in the cross-conjugated, mixed-valent radical anions is proportional to the ferromagnetic contribution to the exchange coupling in the biradical oxidation states. (via Semantic Scholar)

INORGANIC CHEMISTRY, 40(3), 546–549.

By: D. Shultz n, S. Bodnar n, R. Kumar n, H. Lee n & J. Kampf n

TL;DR: Two bis(ZnIIdioxolene) complexes are described in which the two semiquinones are attached to a common carbonyl group and when reacted with PbO2, a labile S = 1, bis( ZnIIsemiquinone) complex is formed. (via Semantic Scholar)

Synthesis and structure of a complex having a quartet ground state with three entirely different spin carriers: Nitronyl nitroxide, o-semiquinone, and Cu-II

INORGANIC CHEMISTRY, 39(26), 6091–6093.

By: D. Shultz n, S. Bodnar n, K. Vostrikova n & J. Kampf n

TL;DR: The results of X-ray structural characterization of the ZnII derivative suggest substantial interaction between the two spin carriers NN and o-SQ, and strong intramolecular exchange coupling has been determined by variable-temperature magnetic susceptibility studies. (via Semantic Scholar)
