In the title dinuclear compound, [V(2)(C(15)H(17)N(2)O)(2)O(4)], each V(V) atom is six-coordinated by one oxide group, and by two N and one O atom of the tridentate Schiff base ligand, and bridged by two additional oxide O atoms, resulting in a centrosymmetric dimer. The metal centre has a distorted octa-hedral coordination with the monoanionic Schiff base ligand occupying one equatorial and two axial coordination positions. The separation between V atoms is 3.214 (3) Å. In the crystal structure, there are N-H⋯O, C-H⋯O and C-H⋯π hydrogen bonds, and π-π inter-actions.
在双核化合物[V₂(C₁₅H₁₇N₂O)₂O₄]中，每个V(V)原子由一个氧基团、三齿席夫碱配体的两个N原子和一个O原子进行六配位，并由另外两个氧O原子桥连，形成一个中心对称的二聚体。金属中心具有扭曲的八面体配位，单阴离子席夫碱配体占据一个赤道和两个轴向配位位置。V原子之间的间距为3.214(3) Å。在晶体结构中，存在N—H⋯O、C—H⋯O和C—H⋯π氢键以及π—π相互作用。
