## Abstract Vanadium(IV) complexes formed in the systems L~2~V^IV^O/AlR~3~, L~2~V^IV^O/AlR~3~/ETA, L~2~V^IV^O/AlR~2~Cl, and L~2~V^IV^O/AlR~2~Cl/ETA, where L is a phenoxyimine ligand (Scheme 1), R = Me or Et, and ETA is ethyltrichloroacetate, were monitored by EPR. It was shown, that at 20 °C, V(IV)
