Evolution of 1H NMR spectra (500 MHz) in the NH region of the [trans-RuCl4(NO)(Hind)]− (a) and [cis-RuCl4(NO)(Hind)]− (b) isomers as a function of time (τ = [0–3] × 105 s) at 100 °C in C2D2Cl4 (C0(trans) = 14.5 mmol/L; C0(cis) = 13.7 mmol/L) showing the formation of the cis and trans isomers, respectively.
