چکیده
In the title compound, C18H18N2O4, the planes of the benzene rings are twisted with respect to each other at 27.25 (7)°. The mol-ecule displays an extended conformation with an intra-molecular O-H⋯N hydrogen bond. In the crystal, weak C-H⋯O inter-actions link the mol-ecules, forming supra-molecular chains running along the b-axis direction.

In the title compound, C22H19N3O3S, the six-membered ring of the 1,2,3,4-tetra-hydro-naphthalene ring system adopts an envelope conformation with the central CH2 C atom as the flap. The mol-ecular conformation is stabilized by an S⋯O contact, forming a pseudo-five-membered ring. In the crystal, mol-ecules are linked via C-H⋯O hydrogen bonds into chains propagating along [102].

The V(IV) atom in the title complex, [V(C(19)H(17)N(3)O(2)S)O], is coordinated by two N and two O atoms of the dianionic tetra-dentate Schiff base ligand and the terminal oxide O atom. The N(2)O(3) donor set defines a square-pyramidal coordination geometry with the oxide O atom in the apical site. Some buckling in the tetra-dentate ligand is indicated by the dihedral angle of 17.92 (19)° betwee...
