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

Abstract

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–.
