Abstract
The elucidation of mechanisms to modulate the properties of multifunctional electroactive, conductive, and magnetic porous materials is desirable to aid their future application. The synthesis and characterization of a two-dimensional (2D) mixed-valence metal-tetraoxolene coordination polymer containing a redox-active dication, (PhenQ)[Fe2(Clan)3]·solvent (1; Clann- = deprotonated 3,6-dichloro-2,5-dihydroxy-1,4-benzoquinone; PhenQ2+ = 5,6-dihydropyrazino[1,2,3,4-lmn][1,10]-phenanthrolindiium), are reported. The PhenQ2+ cation in 1 introduces additional accessible framework redox states and effectively directs the localization of ligand valence states. Static and dynamic magnetic susceptibili..
