摘要
A 36-membered macrocycle with four ethylenediamine entities, 1,1019,28-tetraoxa-4,7,13,1 6,22,25,31,34-octaazacyclohexatriacontane (L), has been synthesized and characterized by H-1 and C-13 NMR and fast atom bombardment (FAB) mass spectra. Its complexing behaviour toward copper(II) ion was investigated spectroscopically and the macrocycle shown to incorporate four copper(II) ions in the range pH 6-9. A tetranuclear complex [Cu4L(OH)4] [ClO4]4.2H2O was obtained and characterized to be of a cubane-type Cu4(OH)4 core surrounded by the macrocycle, according to IR, visible, FAB and ESR spectra, cyclic voltammetry, and cryomagnetic susceptibility.
