μ2-Oxido bridged dinuclear vanadium(V) complex: Synthesis and characterization

4-Bromo-2-[({2-[(2-hy-droxy-eth-yl)amino]-eth-yl}imino)-meth-yl]phenol

The new title Schiff base compound, C11H15BrN2O2, crystallizes in the monoclinic space group P21 with two independent mol-ecules in the asymmetric unit. It was prepared by the condensation reaction of 5-bromo-2-hy-droxy-benzaldehyde and amino-ethyl-ethano-lamine. There is an intra-molecular O-H⋯N hydrogen bond with an S(6) ring motif. Moreover, there are inter-molecular C-H⋯N, C-H⋯O and Br⋯O inter-actions in the crystal structure of the title compound.

Stabilization of two conformers via intra- or inter-molecular hydrogen bonds in a dinuclear vanadium(v) complex with a pendant Schiff base: theoretical insight

A dinuclear vanadium(v) complex, (μ-O)2[V(O)(L)]2, [where HL = 2-methoxy-6-((2-(2-hydroxyethylamino)ethylimino)methyl)phenol] has been synthesized and characterized by spectral and elemental analysis. A single crystal X-ray diffraction study confirms it structure. Two different conformations, stabilized via either intra- or inter-dinuclear hydrogen bonding interactions, co-exist in the solid-state structure. The energies of these intra- or inter-dinuclear hydrogen bonding interactions have been estimated by Density functional theory (DFT) calculations. A 'Non-covalent interaction' (NCI) plot has also been used to characterize these interactions.
