Structure of edta metal complex

WebEDTA called as ethylenediaminetetraacetic acid is a complexometric indicator consisting of 2 amino groups and four carboxyl groups called as Lewis bases. Edta is a hexadentate ligand because of its competence to denote six pair of lonely electrons due to the formation of covalent bonds. WebThe Structures of Complexes For transition metal complexes, the coordination number determines the geometry around the central metal ion. The most common structures of the complexes in coordination compounds are square planar, tetrahedral, and octahedral, corresponding to coordination numbers of four, four, and six, respectively.
