A new tricarbonyl­rhenium(I) compound incorporating the tridentate ligand N,N‐bis­picol­yl‐2‐ethano­lamine

The title compound, {N,N‐bis­(2‐pyridylmeth­yl)­amino]­ethanol‐κ³N,N′,N′′}tricarbonyl­rhenium(I) bromide methanol solvate, Re(C₁₄H₁₇N₃O)(CO)₃]Br·CH₄O, has been prepared in almost quantitative yield by reacting (NEt₄)₂Re(CO)₃Br₃] with the ligand N,N‐bis­picol­yl‐2‐ethano­lamine in refluxing methanol. The X‐ray structure revealed that the Re(CO)₃N₃ coordination sphere is highly distorted from octa­hedral geometry and that the Re(CO)₃ core is facial. The coordinated ligand forms two five‐membered rings, with the pyridine rings in a butterfly formation. The OH group is not involved in metal coordination. The packing of the mol­ecule shows a network of classical O?H—O and Br?H—O, and non‐classical Br?H—C and O?H—C hydrogen bonds between the methanol solvate mol­ecules, the metal complex cations and the bromide anions.
