摘要

Abstract

Triethylenediaminium ethylenediaminetetraacetatozincate trihydrate ([HN(CH2CH2)3NH]ZnL⋅ 3H2О) and tetramethylethylenediaminium ethylenediaminetetraacetatozincate dihydrate ([H(CH3)2NCH2CH2N(CH3)2H]ZnL⋅2H2О) were synthesized by the reaction of zinc oxides with ethylenediaminetetraacetic acid and then with its triethylenediaminum or tetramethylethylenediaminium salts. The synthesized compounds were isolated from aqueous solutions or organic solvents as fiber-like, cubic, and pyramidal crystals, which were characterized by elemental analysis, scanning electron microscopy, IR spectroscopy, thermogravimetry, and differential scanning calorimetry.
