Resumen:
A series of double metal oxalates of stoichiometry MgM(C2O4)2 ⋅4H2O (with M = Mn, Fe, Co, Ni, Zn) have been prepared and characterized. Their structural behavior was investigated by means of X-ray powder diffractometry, showing a strong structural analogy to the so-called β-modification of the related simple oxalate complexes of composition M(C2O4)2⋅2H2O. The vibrational spectroscopic behavior of these double metal oxalates was investigated by infrared and Raman spectroscopy. The structural and spectroscopic results clearly confirmed the strong structural analogies between this new series of double oxalates and those of MM?(C2O4)2⋅4H2O, α-MC2O4⋅2H2O y β-MC2O4⋅2H2O stoichiometry.
