- Аннотация: Protic metal-containing ionic liquids with the diethanolammonium cation (HO–CH2–CH2)2NH2+ (DEAH+) and anions FeCl4(-) and CoCl4(2-) (DEAHFeCl4 (I), (DEAH)2CoCl4 (II)) are synthesized.The crystal structures of compounds I and II are determined by X-ray structure analysis (CIF filesCCDC nos. 1957208 (I) and 1957189 (II)). Compound I has a layered structure. The layer consists of theDEAH+ cations with the disordered system of hydrogen bonds and attached FeCl4(-) anions. The structure ofcompound II represents a three-dimensional framework consisting of the DEAH+ cations and CoCl4(2-)anions linked by hydrogen bonds. The thermal analysis shows that the melting points of compounds I (45°С)and II (55°С) are lower than 100°С, the enthalpy of melting of compound I is higher than that of compoundII, and the decomposition temperature of compound II (210°С) is higher than that of compound I (128°C).
