2-Substituted vs 2,9-Disubstituted Phenanthroline-NiII-halides: Speciation Control and Structural Elucidation in Solution
Herein we study the structures of selected 2,9-disubstituted and 2-monosubstituted phenanthroline NiII-dibromido and diiodido complexes via SC-XRD, SQUID magnetometry, UV–vis–NIR and DOSY NMR. In spite of the divergent speciation in solid state and in DMF solution, the NiII-dibromido complexes of both mono- and disubstituted phenanthrolines converge to monomeric species in both THF and CDCl3. On the other hand, the nickel iodide complexes remain as monomers both in solid state and in solution, regardless of ligand substitution patterns.
The structures of selected 2,9-disubstituted and 2-monosubstituted phenanthroline NiII-dibromido and diiodido complexes are studied via SC-XRD, SQUID magnetometry, UV−vis−NIR and DOSY NMR. The NiII-dibromido complexes of both mono- and disubstituted phenanthrolines converge to monomeric species in both THF and CDCl3. The nickel iodide complexes remain as monomers both in solid state and in solution.
期刊介绍：
Inorganic Chemistry publishes fundamental studies in all phases of inorganic chemistry. Coverage includes experimental and theoretical reports on quantitative studies of structure and thermodynamics, kinetics, mechanisms of inorganic reactions, bioinorganic chemistry, and relevant aspects of organometallic chemistry, solid-state phenomena, and chemical bonding theory. Emphasis is placed on the synthesis, structure, thermodynamics, reactivity, spectroscopy, and bonding properties of significant new and known compounds.
