N2 - The pendant-arm macrocyclic hexa-amine 6,13-dimethyl-1,4,8,11-tetra- azacyclotetradecane-6,13-diamine (L2) co-ordinates to the oxovanadium(IV) cation in a quinquedentate manner. The complex [VO(L 2)][ClO4]2 crystallises in the monoclinic space group C2/c, a = 25.220(4), b = 10.534(2), c = 16.321 (3) Å, β = 94.53(1)°. The vanadium atom is displaced by 0.397 Å above the macrocyclic plane of four nitrogens towards the oxo ligand, with a pendant amine occupying the trans site. Electron paramagnetic resonance and electronic spectra are consistent with the complex being a vanadyl penta-amine in solution as well as in the solid state.
