Copper(II) complexes with some 3-amino-1-propanols

Abstract

Eight copper(II) chloride and bromide complexes with 3-amino-1-propanol and its methyl derivatives were prepared and characterized. In all cases the molar ratio of copper to aminoalcohol was 1:1. 3-Amino-1-propanol, 3-amino-2-methyl-1-propanol and erythro- and threo-4-amino-2-pentanol were used for complexation. The UV and VIS (50000−10 000 cm −1) and IR spectra (4000−100 cm −1) of the copper(II) complexes were measured. The elemental analyses and spectral data suggest that aminoalcohols act as monoanionic, bidentate ligands. Furthermore, the complexes seem to be alkoxobridged square-planar dimes with terminal halogen atoms.
