摘要

The lithium and sodium perchlorate coordination compounds with hexamethylenetetramine of general formulas: [Li(H2O)(4)](+)aEuro cent 2hmtaaEuro cent ClO4 (-) (1) and [Na(ClO4)(H2O)(hmta)](n) (2) have been synthesized, characterised by elemental and thermal analysis, IR spectroscopy and X-ray crystallography. The compound 2 is a rare three dimensional hybrid compound. The obtained compounds are air stable at room temperature and well soluble in water. As a result of the different electronic properties of the ions, the compounds differ considerably in the molecular structure and consequently in the properties. The studied compounds exhibit opposite placement of both hmta molecules and perchlorate ions: in an outer and inner coordination sphere, respectively, for 1 and 2. The thermal and spectroscopic properties were correlated with the studied compounds molecular structure.
