By: M. Kirk*, D. Shultz n, P. Hewitt n, D. Stasiw n, J. Chen* & A. Est*

TL;DR: The frozen solution EPR spectrum of the biradical complex (LZn)(2)()1 exhibits zero-field splitting and a Deltam(s)() = 2 transition characteristic of a triplet state and the temperature dependence of the EPR signal intensity is consistent with high-spin coupling of the unpaired electrons of the ligand.
