Thermal and photochemical control of nitro–nitrito linkage isomerism in single-crystals of Ni(medpt)(NO2)(η2-ONO)

Key Points

• The study investigates how temperature and light affect linkage isomerism in a nickel complex.
• Analyzed [Ni(medpt)(NO2)(η2-ONO)] for isomer ratios between 150–298 K.
• Performed photoactivation experiments at 100 K to observe changes in isomer percentages.
• At temperatures between 150–298 K, an equilibrium between η1-NO2 and η1-ONO isomers is established.
• Upon photoactivation at 100 K, the proportion of the η1-ONO isomer increases significantly.
