Herein, it is summarized that the crystal structures of 17 of FeIII-EDTA, 6 of FeII-EDTA, 21 of CoIII-EDTA, 14 of CoII-EDTA, 13 of Ni-EDTA, 22 of Cu-EDTA, and 7 of Zn-EDTA complexes (total 100 kinds) have coordination numbers (CN) ranging from 5 to 7, most have CN = 6(70/100), and the denticities of these chelates are tetra-, penta-, and hexadentate. In analytical chemistry, typically learned complexes of hexadentate and CN = 6 are found to be only 33 cases (ca. 33%), not major species in the late first-row transition metal-EDTA complexes, following up on the former review., 長崎大学大学院工学研究科研究報告, 53(100), pp.71-78; 2023}, pages = {71--78}, title = {後期第一系列遷移金属-EDTA キレートの比較構造解析}, volume = {53}, year = {2023} }
