• Resumen

  • Two new dimeric dioxovanadium complexes, [VO2L¹]2 (1) and [VO2L²]2 (2), where L¹ and L² are the deprotonated forms of the tridentate Schiff bases 2-[(2-isopropylaminoethylimino)methyl]-4-nitrophenol (HL¹) and 4-bromo-2-[(2-isopropylaminoethylimino)methyl]phenol (HL²), respectively, have been synthesized and characterized by i.r., UV-Vis spectra and single crystal X-ray diffraction. There form two N-H-O hydrogen bonds between two [VO2L] moieties in each complex. The V atom in each complex is coordinated by the three donor atoms of the tridentate Schiff base ligand, and three oxo O atoms, forming an octahedral coordination.
