The behaviour of trans-dihalogenobis(hydrazone)palladium(II) complexes: rotational isomerism or non-equivalence of the two ligands within the same molecule?
Abstract
A detailed 1H n.m.r. analysis of a series of trans-dihalogenobis(hydrazone)palladium(II) complexes has been made in order to demonstrate unequivocally the presence of two rotational isomers differing in the mutual orientation of the co-ordinated ligands.
