| Sumario: | A series of double metal oxalates of stoichiometry MM’(C2O4)2-4H2O (with MM’ = MnCo, MnNi, MnZn, CoNi, CoCu, CoZn, NiCu, NiZn and CuZn have been prepared and characterized. Their structural behavior was investigated by means of X-ray powder diffractometry, showing a strong structural analogy to the orthorhombic, so-called β-modification, of the related simple oxalate complexes of composition MC2O4-2H2O. The vibrational spectroscopic behavior of the double metal oxalates was investigated by infrared and Raman spectroscopy. The results clearly confirmed the close structural analogies between the MM’(C2O4)2-4H2O, β-MC2O4-2H2O and α-MC2O4-2H2O series of complexes. |
