In the title mononuclear dioxidovanadium(V) complex, [V(C₁₃H₁₆BrN₂O₂)O₂], the V^V atom is five-coordinated by one phenolate O, one imine N and one morpholine N atom of the Schiff base ligand, and by two oxide O atoms, forming a distorted square-pyramidal geometry. In the crystal, weak C-HO interactions and a short BrBr contact [3.4597 (12) Å] are observed.
