抄録	To obtain a novel type of low-coordinate, low-valent complexes of cobalt, we performed synthesis and reactions of cobalt complexes supported by TDAR ligands, which possess highly electron-donating amide groups with a terphenyl framework. Synthesis of TDARCo(I) complexes 3 and 4 was successfully achieved by reducing Co(II) precursors 1 and 2 with potassium graphite. X-ray crystallography revealed that the cobalt centers are located close to the central aromatic rings of the TDAR ligands, and the reduction of Co(II) to Co(I) strengthens this Co–arene interaction. Reaction of the cobalt(I) complexes with pyridine or DMAP provided N-donor ligated complexes 5 and 6. Surprisingly, the Co–aromatic ring interactions in these complexes were found to be even stronger than those in 3 and 4. These interactions with the aromatic rings were investigated in detail using computational methods.
