Resumen

New double complex salts Co(NH₃)₅ClCu(H₂O)(C₂O₄)₂ and Co(en)₃₂Cu(H₂O)(C₂O₄)₂₂Cu(H₂O)₂(C₂O₄)₂·10H₂O (en — ethylenediamine) have been synthesized and their thermal properties studied. The compounds were characterized using various physicochemical methods (PXRD, SCXRD, IR spectroscopy, elemental analysis). It has been established that upon decomposition of these complex salts, metastable solid solutions CoxCu₁₋ₓ with high mutual metal solubility are formed.
