The ligand (py)2CHPh is formed on reaction of (2-benzylpyridy1)lithium with 2-bromopyridine. 1H NMR spectra indicate that (py)2CHPh and (py)2(N-Me1m)COH are present as bidentates in methanol solutions of their complexes, with the latter coordinated via the imidazolyl ring and one pyridyl ring. Spectra are consistent with the presence of weak pi interactions between mercury and phenyl rings in the&#13;
