| Several new [MnIII(methoxytetraphenylporphyrin)][TCNE] (TCNE = tetracyanoethanide) molecule-based magnets have been synthesized and demonstrate the relationship between intrachain coupling and the weak effect on the ordering temperature concluding that the dipolar interactions are responsible for higher ordering temperature magnets of this family. The first structurally characterized isolated [TCNQF4]·− (TCNQF 4 = 2,3,5,6-tetrafluoro-7,7,8,8-tetracyano-p-quinodimethane) was found to magnetically order at 7.3 K. Along with the [TCNQMe2 ] analog (TCNQMe2 = 2,6-dimethyl-7,7,8,8-tetracyano- p-quinodimethane) has allowed investigation into the effects of greater spin delocalization of the radical bridging ligand on the intrachain coupling. The Tl(I) salts of [TCNE]·− and [TCNE] 2− have been synthesized and their general utility has been demonstrated in several anion exchange reactions. To add to the small number of stable organic radical anions, an investigation into the synthesis of 2,3,6,7,10,11-hexacyanotriphenylene was also conducted; which, resulted in several new compounds that may be of interest as precursors for triphenylene-based discotic mesogens or asymmetric phthalocyanines synthesis. |
