The paper presents the experimental results of the structural investigations and thermal analysis of a new cobalt(II)-polynuclear coordination compound having as ligand 3-hydroxypropionate anion (L), which is oxidation product of 1,3-propanediol. The reaction between 1,3-propanediol and Co(NO3)26H2O occurs, under some working conditions, with the oxidation of 1,3-propanediol to the 3-hydroxypropionate anion. The synthesized polynuclear coordination

The results of an investigation concerning the reaction between 1,2-propanediol and Co(NO3)26H2O, leading to a complex containing as ligand the lactate anion (L) are presented. The obtained solid homopolynuclear coordination compound [Co2(OH)2L2(H2O)20.5H2O]n , has been investigated by thermal analysis, electronic and IR spectroscopy and magnetic methods. Cobalt oxide obtained by thermal decomposition of these coordinative compound was characterized
