The [Co4ĲNPy3)2Ĳadb)4]n framework (1) containing a new (3,7)- c topology mmg has been constructed from the combination of a rare 7-c Co dimer node and a 3-c redox-active trisĲ4- (pyridin-4-yl)phenyl)amine (NPy3) ligand with the light active 4,4′-azodibenzoic acid (H2adb) serving as a linear linker. The 7-c Co dimer node contains five relatively equal coordination points in one plane resulting in rare 5-fold symmetry. Solid state electrochemical and vis-NIR spectroelectrochemical studies on the framework determined the accessibility of the triarylamine radical cation state.
