The search for molecules with novel electronic properties is one focus of modern magnetochemistry. Open-shell species comprised of multiple, chemically different paramagnetic functional groups are candidates for exploration. Examples of interesting, yet simple spin diverse species are heterospin biradical ligands (biradicals in which the paramagnetic functional groups are different). Here we will report the synthesis and characterization of a few metal complexes of heterospin biradical ligands. The biradical ligands are comprised of semiquinone (SQ) and nitronyl nitroxide (NN) moieties. The effects of different spacers between NN and SQ is explored. Complexes reported include the SQ-NN, the phenyl spaced SQ-NN, the thiophene spaced SQ-NN, and the ethylene spaced SQ-NN ligands.
