Journal ArticleDOI
2,2′:6′,2″-Terpyridine (terpy) acting as a fluxional bidentate ligand. Part 2. Rhenium carbonyl halide complexes, fac-[ReX(CO)3(terpy)](X = Cl, Br or I): NMR studies of their solution dynamics, synthesis of cis-[ReBr(CO)2(terpy)] and the crystal structure of [ReBr(CO)3(terpy)]
Edward W. Abel,Valentin S. Dimitrov,Nicholas J. Long,Keith G. Orrell,Anthony G. Osborne,Helen M. Pain,Vladimir Šik,Michael B. Hursthouse,Mohammed A. Mazid +8 more
TL;DR: In this article, the X-ray crystal structure of fac-[ReBr(CO)3(terpy)] confirms the bidentate chelate bonding of terpy with a N-Re-N angle of 74.3°.
Journal ArticleDOI
2,2′:6′,2″-Terpyridine (terpy) acting as a fluxional bidentate ligand. Part 4. cis-[M(C6F5)2(terpy)](M = Pd or Pt): nuclear magnetic resonance studies of their solution dynamics and crystal structure of cis-[Pd(C6F5)2(terpy)]
Edward W. Abel,Keith G. Orrell,Anthony G. Osborne,Helen M. Pain,Vladimir Šik,Michael B. Hursthouse,K. M. Abdul Malik +6 more
TL;DR: In this article, the rate of terpyridine fluxion was measured by NMR spectroscopy from the exchange effects on the 1H signals of the aromatic hydrogens and in the 19F signals of two C6F5 groups.
Journal ArticleDOI
2,2′:6′,2″-Terpyridine (terpy) acting as a fluxional bidentate ligand. Part 1. Trimethylplatinum(IV) halide complexes [PtXMe3(terpy)](X = Cl, Br or I): nuclear magnetic resonance studies of their solution dynamics and crystal structure of [PtIMe3(terpy)]
Edward W. Abel,Valentin S. Dimitrov,Nicholas J. Long,Keith G. Orrell,Anthony G. Osborne,Vladimir Šik,Michael B. Hursthouse,Mohammed A. Mazid +7 more
TL;DR: In this paper, the terpyridine (terpy) reacts with trimethylplatinum halides to form stable octahedral complexes fac-[PtXMe3(terpy)](X = Cl, Br or I) in which the terpy molecule is acting as a bidentate chelate ligand.
Journal ArticleDOI
[3]Ferrocenophane bridge reversal barriers
TL;DR: In this paper, the authors used dynamic NMR data for the bridge reversal fluxion of ferrocenophanes with Group VI bridging atoms and made estimates of the relative magnitudes of torsional barriers about single bonds involving like and unlike Group VI atoms.
Journal ArticleDOI
The first examples of 2,2′:6′,2″-terpyridine as a fluxional bidentate ligand
Edward W. Abel,Nicholas J. Long,Keith G. Orrell,Anthony G. Osborne,Helen M. Pain,Vladimir Šik +5 more
TL;DR: In this article, the ligand oscillates between equivalent bidentate forms by a mechanism involving a "tick-tock" twist of the metal moiety through an angle equal to the N-M-N angle of the octahedral centre and involving a seven-coordinate metal intermediate.
