(Arylimido)triethanolaminatovanadium(V) compounds, [V( p ‐RC 6 H 4 N)(TEA)] (R = NMe 2 , OMe, Me, H, Cl, Br, CN), were synthesised by ligand exchange reaction of the corresponding (arylimido)triisopropoxidovanadium(V) complexes, [V(O i Pr) 3 ( p ‐RC 6 H 4 N)], which were prepared by the reaction of VO(O i Pr) 3 with various p ‐substituted aryl isocyanates without solvent. Structural characterisation of the (arylimido)triethanolaminatovanadium(V) products was carried out bysingle‐crystal X‐ray diffraction in order to elucidate the substituent effect on the imido structures, in which the imido structures were found to be controlled through π conjugation by the para substituents of the aryl moieties.
