摘要

Double complex salts (DCSs) [Co(NH_3)_6][Fe(CN)_6] (I) and [Co(NH_3)_6]_2[Cu(C_2O_4)_2]_3 (II)and complex [Co(NH_3)_6]_2(C_2O_4)_3 ·4H_2O (III) are synthesized and investigated by single crystal XRD, crystal optics, and elemental analysis. The crystalline phases of I, II, and III (R -3, P2_1/c, and Pnnm space groups respectively) have the following crystallographic characteristics: a = 10.9804(2) ?, b = 10.9804(2) ?, c = 10.8224(3) ?, V = 1130.03(4) ?~3, Z = 3, d_x = 1.65 g/cm~3 (I); a = 9.6370(2) ?, b = 10.2452(2) ?, c = 13.2108(3) ?, V = 1932.90(9) ?~3, Z = 2, d_x = 1.97 g/cm~3 (II), and a = 11.7658(3) ?, b = 11.7254(3) ?, c = 14.1913(4) ?, V = 1304.34(5) ?~3, Z = 2, d_x = 1.68 g/cm~3 (III). This paper investigates the products of DCS thermolysis in a hydrogen atmosphere: the intermetallic compound CoFe with the bcc parameter a = 2.852 ? for I and a heterogeneous mixture of Co and Cu in the decomposition of II. The coordinated CN~? and C_2O_(~(2?)4) groups then turn into NH3, hydrocarbons, and CO_2. The dominant hydrocarbon is methane.
