Abstract
The reaction between mer-[Re(O)CI3(L-L)] [L-L = 2,2' -bipyridine (bipy) or 4,4'- dimethyl-2,2'bupyridine] and aniline in refluxing 0-xylene gave phenylimido compounds formulated as mer-[Re(NPh)-CI3(L-L)]. These compounds do not react with an alcohol (ROH) to form alkoxyimido compounds of the type cis-[Re(NPh) (OR) CI2(L-L)], but in the presence of an excess of the polypyridyl ligand, salts of the cation trans-[Re(NPh) (OEt) (L-L2]2+ were obtained. When salts of trans-hydrochloric acid rapid reactions occurred that resulted in the isolation of mer-[Re(NPh)CI3(L-L) ]. The salt trans-[Re(NPh)CI2(terpy)]PF6 was prepared from the reaction between mer-trans-[Re(NPh)-CI3(PPh3)2] and 2,2' :6',2'2 -terpyridine (terpy) in refluxing ethanol. The spectroscopic and electro-chemical properties of these compounds were investigated and the structures of mer-[Re(NPh)-CI3(biby) ] , trans- [Re(NPh) (OEt) (bipy)2] [PF6]2 and trans-[Re(NPh)CI2(terpy) ]PF6 determined by X-ray crystallography....
