Аннотация: Reactions of [Co(NH3)6]Cl3 and K3[Co(C2O4)3] in aqueous solutions result in formation of a new double complex salt, [Co(NH3)6][Co(C2O4)3] (1). The crystal structure of 1 is triclinic [space group , a = 7.5180 (5) Å, b = 9.4283 (5) Å, c = 11.4968 (7) Å, α = 84.018 (4), β = 87.508(4), γ = 71.254(4)°] and is derived from a CsCl archetype. It is analogous to the previously reported [Ir(NH3)6][Co(C2O4)3] and [Co(NH3)6][Ir(C2O4)3], which are also triclinic and crystallize in the space group . The difference in the number of water molecules in comparison with the previously studied [Co(NH₃)₆][Co(C₂O₄)₃]·3H2O (sp. gr. P ) can be explained by different methods for obtaining single crystals suitable for X-ray diffraction analysis. These findings expand the data pool on double complex salts with cations and anions based on the same transition
