Abstract

From the CoCl2-1-amino-8-hydroxynaphthalene-2,4-disulfonic acid-benzoin (or benzaldehyde and its para- and ortho-hydroxy derivatives), complexes of the composition C48H38K2N2O18S4Co, C17H17ClKNO11S2Co, C17H16KNO11S2Co, and C34H24K2N2O16S4Co2 were isolated. These compounds were identified and characterized by elemental and X-ray phase analysis, thermogravimetry, IR and diffuse reflectance spectroscopy, as well as magnetic susceptibility and electroconductivity measurements. The C17H16KNO11S2Co and C34H24K2N2O16S4Co2 complexes were additionally studied by the extended X-ray absorption fine structure (EXAFS) method. Evidence for a monomeric structure of the former complex and for a hydroxyl-bridged dimeric structure of the latter was obtained.
