Di-μ-oxido-bis[(2-ethoxy-6-{[2-(2-hydroxyethylamino)ethylimino]methyl}phenolato-κ³N,N′,O¹)oxidovanadium(V)]

Abstract

In the title centrosymmetric dinuclear dioxidovanadium(V) complex, [V2(C13H19N2O3)2O4], the VV ion is coordinated by an N,N′,O-tridendate 2-eth­oxy-6-{[2-(2-hy­droxy­ethyl­amino)­ethyl­imino]­meth­yl}phenolate ligand and three oxide O atoms, forming a distorted cis-VN2O4 octa­hedral geometry. The bridging O atoms show one short and one long bond to their two attached VV atoms. The dihedral angle between the benzene ring of the ligand and the V2O2 plane is 75.2 (3)°. The deviation of the VV ion from the plane defined by the three donor atoms of the tridentate ligand and one bridging oxide O atom is 0.337 (2) Å towards the terminal oxide O atom. Two N—H⋯O hydrogen bonds help to establish the conformation of the dimer. In the crystal, the complex mol­ecules are linked by O—H⋯O hydrogen bonds, forming [100] chains.
