The electronic absorption spectrum of crystals of the title compound [Pb.Ni(HEDTA) H 2 O] Cl was recorded and discussed quantitatively. Using ligand field theory and the radial wave function of bound Ni(II) ion, the d‐d transition energy levels of crystals of [Pb.Ni(HEDTA) H 2 O] Cl, Ca [Ni(EDTA)] · 4H 2 O, [Li.Ni(HEDTA) H 2 O], [NiH 2 EDTA)H 2 O] were calculated. The different structure characteristics of EDTA's metal complexes are evidently shown in their d‐d transition spectra.
