Abstract
Flexible 1,5-bis(salicilydene)carbohydrazone ligand in combination with an in situ formed divanadium [V2O3]4+ core afforded one discrete tetranuclear complex and two polymeric chain-like architectures, mutually related as supramolecular isomers. The occurrence of a particular isomer was controlled through the reaction conditions. All isolated products were structurally characterized via X-ray diffraction and infrared spectroscopy, while the relative stability of the architectures was assessed via competitive slurry and thermal experiments. This study highlights the adaptability of oxovanadium species towards the coordination “inventory” of building blocks present in the environment, while at the same time it unveils the richness of assembly modes of the related structural units.
