Popis:	Two new dioxovanadium(V) complexes, [VO2L1]2 (1) and [VO2L2] (2), where L1 and L2 are the deprotonated forms of 4-chloro-2-[(2-isopropylaminoethylimino)methyl]phenol and 4-chloro-2-[(2-morpholin-4-ylethylimino)methyl]phenol, respectively, have been synthesized and characterized by IR spectra and single crystal X-ray diffraction. Complex (1) is a centrosymmetric dinuclear dioxovanadium complex, with the V atom six-coordinate in an octahedral geometry. The V⋅⋅⋅V distance is 3.224(2) A. Complex (2) is a mononuclear dioxovanadium complex, with the V atom five-coordinate in a distorted square pyramidal geometry. The steric effects of the terminal groups in the Schiff base ligands can influence the structures of the complexes.
