Аннотация:Two new compounds, trichloro[O-bis(2-hydroxyethyl)ammonium] manganese(II),{Mn[(HOCH2CH2)2NH2]Cl3}n, (1), and N-(2-hydroxyethyl)-N-methylammoniumaquatrichloromanganate(II), [CH3NH2CH2CH2OH][Mn(H2O)Cl3] (2), were synthesized.The crystal structures of the new compounds were determined by single-crystal X-raydiff raction. Both structures contain similar chains composed of (MnOCl5) octahedra.In the structure of 1, the manganese atom is coordinated by the OH group of the cation;in the structure of 2, the manganese atom is coordinated by a water molecule. There arediff erent hydrogen bond systems in the structure of 1 due to disorder of OH groups of thecation. The melting points and enthalpies of the synthesized compounds evaluated by DSCare 162 oC and 17.3 kJ mol–1 for compound 1 and 30 C and 16.9 kJ mol–1 for compound 2,respectively. Compound 1 is a chain coordination polymer, while compound 2 is anionic liquid with a polynuclear anion.
