The new ligand 6-(2-aminophenyl)-2,2 -bipyridine (L) was prepared in high yield by demethylation of 6-(2-N,N-dimethylaminophenyl)-2,2 -bipyridine, and contains two pyridyl donors and one aniline donor. It coordinates as a terdentate N-donor ligand to both first-row and second-row transition-metal ions. The crystal structure of [ZnL 2 ][PF 6 ] 2 MeOH reveals that each ligand...
Reaction of Zn(CH 3 CO 2 ) 4H 2 O with the N,N,O-terdentate chelating ligand HL 1 (HL 1 = 6-(2-hydroxyphenyl)-2,2 -bipyridine) followed by NaBPh 4 affords [Zn(L 1 ) 2 (BPh 2 )][BPh 4 ], in which the two cis-oriented phenolates, which are weakly coordinated to the six-coordinate Zn(II) centre, also both bond to a {BPh...
