Ligand Control of ⁵⁹Co Nuclear Spin Relaxation Thermometry.

ABSTRACT: Studying the correlation between temperature-driven molecular structure and nuclear spin dynamics is essential to understanding fundamental design principles for thermometric nuclear magnetic resonance spin-based probes. Herein, we study the impact of progressively encapsulating ligands on temperature-dependent ⁵⁹Co T ₁ (spin-lattice) and T ₂ (spin-spin) relaxation times in a set of Co(III) complexes: K₃[Co(CN)₆] (1); [Co(NH₃)₆]Cl₃ (2); [Co(en)₃]Cl₃ (3), en = ethylenediamine); [Co(tn)₃]Cl₃ (4), tn = trimethylenediamine); [Co(tame)₂]Cl₃ (5), tame = triaminomethylethane); and [Co(dinosar)]Cl<
