Abstract
The coordination chemistry of 2‐(2′‐pyridyl)‐4,6‐diarylphosphinines towards ReI has been investigated and compared to the structurally analogous 2,2′‐bipyridine derivatives. The different steric properties of the chelating pyridylphosphinines with respect to substituted bipyridines lead to considerable differences in the structures of the mononuclear [(P^N)Re(CO)3X] and [(N^N)Re(CO)3X] (X = Cl, Br) complexes, both
