title: Di-μ-oxido-bis-[(2-eth-oxy-6-{[2-(2-hy-droxy-ethyl-amino)-ethyl-imino]-meth-yl}phenolato-κN,N',O)oxidovanadium(V)].
abstract: In the title centrosymmetric dinuclear dioxidovanadium(V) complex, [V(2)(C(13)H(19)N(2)O(3))(2)O(4)], the V(V) ion is coordinated by an N,N',O-tridendate 2-eth-oxy-6-{[2-(2-hy-droxy-ethyl-amino)-ethyl-imino]-meth-yl}phenolate ligand and three oxide O atoms, forming a distorted cis-VN(2)O(4) octa-hedral geometry. The bridging O atoms show one short and one long bond to their two attached V(V) atoms. The dihedral angle between the benzene ring of the ligand and the V(2)O(2) plane is 75.2 (3)°. The deviation of the V(V) 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 mol-ecules are linked by O-H⋯O hydrogen bonds, forming [100] chains.
