Abstract: The green colored complexes of the type ReVO(LSB)Cl2, 1, have been synthesised by reacting NBu4[ReOCl4] with HLSB in dry ethanol. Here, LSB− are the deprotonated forms of N-(2-hydroxybenzyl)-2-picolylamine (HLSB1); N-(2-hydroxybenzyl)-N′,N′-dimethylethylenediamine (HLSB2) and N-(2-hydroxybenzyl)-N′,N′-diethylethylenediamine (HLSB3). Similarly, NBu4[ReOCl4] reacted with N,N-bis(2-hydroxybenzyl)-2-picolylamine (H2L1); N,N-bis(2-hydroxybenzyl)-N′,N′-dimethylethylenediamine (H2L2); N,N-bis(2-hydroxybenzyl)-N′,N′-diethylethylenediamine (H2L3); {N-(2-hydroxybenzyl)-N-(2-pyridylmethyl)}-2-aminoethanol (H2L4); {N-(2-hydroxybenzyl)-N-(2-pyridylmethyl)}-2-methyl-2-amino-1-propanol (H2L5); N,N-bis(1-hydroxyethyl)-2-picolylamine (H2L6), to give the monochloro complexes ReVO(L)Cl, 2. The X-ray structures of the complexes are reported. The molecular structures observed in the solid state are preserved in solution (1H NMR). In acetonitrile solution the ReVO(L)Cl, 2, display a one-electron couple, ReVIO(L)Cl+–ReVO(L)Cl, near 1.0 V vs SCE. The electrogenerated hexavalent complexes [ReVIO(L)Cl]ClO4, 3, are paramagnetic and display sextet EPR spectra in solution at room temperature (Aav ∼ 417 (G), g ∼ 1.914).
