| Abstract: | The synthesis and spectroscopic characterization of quaternary salts containing 2,2,-bipyridine, 1,10-phenanthroline, 4,7-dimethyl-1,10-phenanthroline and 3,4,7,8-tetramethyl-1,10-phenanthroline is reported. The coordinating behaviour of the bipyridylium salts toward palladium, copper and dimethyltin(IV)halides is investigated. The reaction of N-R,2,2′-bipyridylium (= L1) bromide (R = 4-Cl-C6H4 · CO · CH2) with palladium(II) chloride in acetonitrile solution yields a crystalline product, shown by a single crystal X-ray study to be L1PdX3, where X is a Cl/Br (1:1) composite. |
