چکیده

A new monoclinic polymorph of the title compound, [V(2)(C(10)H(13)N(2)O)(2)O(4)], which is a centrosymmetric dimer, crystallizes in space group P2(1)/c, whereas the previously known polymorph crystallizes in the ortho-rhom-bic space group Pbca [Mokry & Carrano (1993 ▶). Inorg. Chem.32, 6119-6121]. Each V(V) atom is six-coordinated by one oxide group, two N atoms and one O atom from the Schiff base ligand, and by two additional bridging O atoms. The two methyl-ene groups are each disordered over two sites, with occupancy factors of 0.776 (14) and 0.224 (14). In the crystal structure, there are C-H⋯O hydrogen bonds and C-H⋯π inter-actions between the dimers.

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) at...
