2-Substituted vs 2,9-Disubstituted Phenanthroline-Ni<sup>II</sup>-halides: Speciation Control and Structural Elucidation in Solution
Herein we study the structures of selected 2,9-disubstituted and 2-monosubstituted phenanthroline Ni<sup>II</sup>-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 Ni<sup>II</sup>-dibromido complexes of both mono- and disubstituted phenanthrolines converge to monomeric species in both THF and CDCl<sub>3</sub>. On the other hand, the nickel iodide complexes remain as monomers both in solid state and in solution, regardless of ligand substitution patterns.
