Chemistry of pyrrocorphins: structure of nickel(II)ccccc-octaethyl-pyrrocorphinate in the solid state and in solution. Observation of the inversion barrier between enantiomorphically ruffled conformers

Abstract
An inversion barrier between enantiomorphic saddle conformers of nickel(II)ccccc-octaethyl-pyrrocorphinate in solution is observed by 1H n.m.r. spectroscopy.
