Solubility of d-Element Salts in Organic and Aqueous-Organic Solvents: VI.1 Structure and Thermal Stability of Cadmium Iodide and Bromide Solvates with Dimethylacetamide and Dimethylformamide

Five solvates, [CdBr2(DMF)] (n) , [CdBr2(DMA)] (n) , [CdI2(DMF)] (n) , [Cd(DMF)(6)][Cd2I6], and {[Cd(DMA)(6)][Cd5I12] (n) } (m) , were isolated from the ternary systems CdX2-L-H2O (X = Br, I; L = N,N-dimethylacetamide, N,N-dimethylformamide) and characterized by the X-ray single crystal analysis. The structures of the first three solvates is similar to each other in structures and represent a one-dimensional polymer chain, the fourth solvate has the discrete structure containing [Cd(DMF)(6)](2+) and [Cd2I6](2-) ions, and the fifth solvate contains discrete [Cd(DMA)(6)](2+) cations and the polymer anionic fragment [Cd5I12] (n) (2n-).
