Correlations between ligand field <i>Δ</i><sub>o</sub>, spin crossover <i>T</i><sub>1/2</sub> and redox potential <i>E</i><sub>pa</sub> in a family of five dinuclear helicates
Sandhya Singh, Sally Brooker
Abstract
Choice of non-coordinated diazole heteroatom in five robust triply bridged dinuclear helicates tunes Δ o , spin crossover and redox potential. Regardless of fraction high spin (0–0.81), DOSY NMR confirms the helicates are intact in solution.
