Cu(II), Cr(III), VO(II) and Mn(II) chelates of 5-amino-1-(aryl)imidazole-4-carboxamide, aryl = C6H5-, -C6H4CH3, and -C6H4OCH3 were prepared and characterized by microchemical analyses, infrared and electronic spectra and thermogravimetric analyses. IR spectra showed that the ligands behave in a bidentate manner. Also, octahedral structures are proposed for the Cr(III) and Mn(II) chelates, whereas square-planar and square-pyramidal structures are proposed for the Cu(II) and oxovanadium(IV) chelates, respectively.
