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.
在标题中心对称双核二氧化钒（V）配合物[V₂(C₁₃H₁₉N₂O₃)₂O₄]中，V（V）离子由一个N，N′，O-三齿2-乙氧基-6-{[2-(2-羟基-乙基-氨基)-乙基-亚氨基]-甲基}酚盐配体和三个氧原子配位，形成一个扭曲的顺式-VN₂O₄八面体几何构型。桥连氧原子与其两个相连的V（V）原子形成一个短键和一个长键。配体的苯环与V₂O₂平面之间的二面角为75.2 (3)°。V（V）离子相对于由三齿配体的三个供体原子和一个桥连氧化物氧原子所定义平面的偏差为0.337 (2) Å，朝向末端氧化物氧原子。两个N-H⋯O氢键有助于确定二聚体的构象。在晶体中，配合物分子通过O-H⋯O氢键相连，形成[100]链。
