| Abstract: | The new orotic acid complexes, MCl2(H2O)3(H3Or)], M=Co(II), Ni(II) and CuCl2(H2O)(H3Or)3] · H2O, were synthesized and characterized by elemental analysis, magnetic susceptibility, spectral (Diffuse reflectance UV–Vis
and FTIR) methods, and simultaneous thermal analysis (TG, DTG and DTA) techniques. Physical measurements indicate that the
neutral orotic acid ligands are bonded to metal ions through the carbonyl groups. Two thermal processes of the complexes can
occur: dehydration and pyrolytic decomposition. On the basis of the DTGmax, the thermal stability of the complexes follows the order: Co(II) (122 °C) > Cu(II) (77 °C) > Ni(II) (66 °C). |
