N2 - Double complex compounds (DCC) of the [Cr(ur)6][Fe(CN)6]·4H2O (I), [Cr(ur)6][Co(CN)6]·4H2O (II), [Cr(ur)6][Fe(Ox)3]·2H2O (III), and [Cr(ur)6][Co(Ox)3].3.5H2O (IV) composition, where ur is CO(NH2)2, Ох – С2О4 2− have been synthesized and their crystal structures have been studied. The DCC I, II and IV are triclinic (Р-1); III is orthorhombic (С2221). The DCC thermal behavior in air and argon atmospheres was analyzed by the following parameters: the temperature interval of total decomposition and the nature of gaseous and solid products. The end solid products in air were FeO and FeCr2O4 for I, a mixture of СоCr2O4 + Со2CrO4 for II and IV and an X-ray amorphous phase with composition CrFeO2.5 for III. The gaseous products were HCN, NH3, HNCO, N2O, СО, СО2, N2, and urea. The temperatures of total decomposition in air were: I, II 400°С, III – 350°С, IV – 460°С. In argon, the solid residue contained, besides the oxides, 7–30% of carbon up to 1000°С.
