| description | The title compound, [CdBr2(C6H8N2)]n, was prepared by the reaction of cadmium bromide with 2,5-dimethylpyrazine in water. Its asymmetric unit consists of one Cd cation and one 2,5-dimethylpyrazine ligand that are located on a crystallographic mirror plane as well as one bromide anion that occupies a general position. The Cd cations are sixfold coordinated by four bromide anions and two 2,5-dimethylpyrazine ligands within slightly distorted trans-CdBr4N2 octahedra. The cations are linked into [100] chains via pairs of bridging bromide anions that are further connected into (001) layers by the bridging 2,5-dimethylpyrazine ligands. Powder X-ray diffraction (PXRD) shows that a pure crystalline phase has been obtained. Thermogravimetry coupled to differential thermoanalysis (TG-TDA) reveal that the 2,5-dimethylpyrazine ligands are removed in two separate steps leading to the formation of a compound with the composition (CdBr2)2(2,5-dimethylpyrazine) that decomposes into CdBr2 upon further heating. PXRD measurements of the residue obtained after the first mass loss show that a new crystalline phase has been formed. |
