Abstract

A new triazamacrocycle, 1,6,11-triazacyclopentadecane (tacpd), has been synthesized and its complexation behaviors toward nickel(II), copper(II) and zinc(II) ions have been examined. tacpd formed a Zn(II) complex of the composition Zn3(tacpd)2Cl6 but no discrete complexes with Ni(II) and Cu(II) ions. The 1H and 13C NMR spectra indicated that the zinc complex is stable in N,N-dimethylformamide and formulated as [Zn(tacpd)Cl]2[ZnCl4] in which [Zn(tacpd)Cl]+ assumes a tetrahedral structure formed by the chloride ion and three nitrogens of tacpd.
