X-ray study indicated two stable rotamers in case of compounds containing 2-thienyl and 2-furyl substituents. DFT calculations well interpreted structural parameters of all studied complexes. Calculations of potential energy surfaces (PES) for neutral species confirmed existence of two energy minima on the potential energy surfaces. Calculated rotation barriers increase in the series 2-furyl, 2-thienyl and N-methyl-2-pyrrolyl, respectively. The PES scans for compounds in one-electron reduced states essentially reveal opposite behavior to the one observed for neutral complexes. Connection is drawn between the observed structural flexibility and electrochemical properties of the compounds."@en .
