Syntheses, Crystal Structure, and Properties of Cu(II) and Zn(II) Complexes with EDO-TTF-3-py

Abstract

The syntheses, crystal structures, and electrochemical of the transition metal coordination complexes, Cu(acac)₂(EDO-TTF-3-py)₂ (2) and Zn(acac)₂(EDO-TTF-3-py)₂ (3) are reported, where acac = acetylacetonate; EDO-TTF-3-py (L1) = 4,5-ethylenedioxy-3′-(3′-pyridyl)-tetrathiafulvalene). In the complexes 2 and 3, the ligand L1 is coordinated to the metal atom through pyridine nitrogen. The similarly oxidation potentials were observed for the ligand L1 and 2 and 3, indicating the negligible interaction between the ligand and the metal in solution.

Keywords:
