## Abstract The complete assignment of the proton and carbon spectra for two new 2‐pyridylquinoline ligands, 4‐phenyl‐2‐(2′‐pyridyl)quinoline (Ph‐pq) and 2,6‐di(4′‐phenylquinol‐2′‐yl)pyridine (Ph‐dqp), and their ruthenium(II) complexes [Ru(bpy)~2~(Ph‐pq)](PF~6~)~2~ and [Ru(Ph‐dqp)~2~](PF~6~)~2~ has
## Abstract ^1^H NMR data of α‐[Ru(azpy)~2~(MeBim)~2~](PF~6~)~2~ (azpy=2‐phenylazopyridine, MeBim=1‐methylbenzimidazole), 2, revealed the presence of a total of seven atropisomers at −95 °C: three head‐to‐tail, HT, isomers (A, C, and D), and four head‐to‐head, HH, isomers which, due to the presence
