- Linkage isomerism in transition-metal complexes of mixed (arylcarboxamido)(arylimino)pyridine ligands
-
The synthesis of a series of asymmetric mixed 2,6-disubstituted (arylcarboxamido)(arylimino)pyridine ligands and their coordination chemistry toward a series of divalent first-row transition metals (Cu, Co, and Zn) have been explored. Complexes featuring both anionic N,N,N″-carboxamido and neutral O,N,N-carboxamide coordination have been prepared and characterized by X-ray crystallography, cyclic voltammetry, and UV-visible and EPR spectroscopy. Specifically, RLM(X) (M = Cu; X = Cl-, OAc-) and RL(H)MX2 (M = Cu, Co, Zn; X = Cl-, SbF 6-) complexes that feature N,N,N″- or O,N,N-coordination are presented. Base-induced linkage isomerization from O,N,N-carboxamide to N,N,N″-carboxamido coordination is also confirmed by multiple forms of spectroscopy.

- Polynuclear lanthanide complexes of a series of bridging ligands containing two tridentate N,N′,O-donor units: Structures and luminescence properties
-
A set of three potentially bridging ligands containing two tridentate chelating N,N′,O-donor (pyrazole-pyridine-amide) donors separated by an o, m, or p-phenylene spacer has been prepared and their coordination chemistry with lanthanide(iii) ions investig
