Reaction of with SnCl2 (1/1) in refluxing xylene gives the monoaryl complex (I) and Hg.Complex I reacts with excess of NaBr to give (II) and with HgPh2 (1/1) to give (III), which reacts with 1,10-phenanthroline (phen) to give (IV); this in turn, reacts with Na, to give the cationic complex (V).The complex reacts with excess of NaBr or KSCN to give the corresponding (X = Br (VI), NCS (VII)) complexes, and with AgClO4 to give AgCl and a solution from which, by addition of pyridine (py), the complex (ClO4)2 (VIII) can be isolated.
