1-Ethoxycarbonyl-3-ferrocenyl-propan-1,3-dion und Ferrocen-1,1'bis(2,4-dioxobutansäureethylester) als Liganden für Übergangsmetallionen. Kristallstruktur von Bis(1-ethoxycarbonyl-3-ferrocenyl-propan-1,3dionato)kupfer(II)
摘要:
The ligands 1-ethoxycarbonyl-3-ferrocenyl-propane-1,3-dion and ferrocene-1,1'-bis(2,4-dioxo-butanoic acid ethylester) have been prepared by reaction of acetylferrocene or 1,1'-diacetylferrocene and diethyl oxalate. They yield neutral chelates with Cu-II, Ni-II, Zn-II, Co-II, and Mn-II. The acid dissociation constants of the ligands and the stability constants of their metal complexes including Fe-II complexes are reported. The structure of bis(1-ethoxycarbonyl-3-ferrocenyl-propane-1,3-dionato)copper(II) was determined by Xray structure analysis. A cis arrangement with a nearly square planar coordination sphere at the Cu atom is found.
