the nickel(II) complexes with no derivatized edta-type hexadentate ligands has been investigated from their structural and electronic properties. Two more complexes have been prepared in order to complete the whole set: trans(O5)-[Ni(ED3AP)]2- and trans(O5O6)-[Ni(EDA3P)]2- complexes. trans(O5) geometry has been verified crystallographically and trans(O5O6) geometry of the second complex has been predicted

A new hexadentate chromium(III) complex with ethylenediamine-N-acetic-N,N',N'-tri-3-propionic acid [H-4eda3p) is reported. Only one (trans(O5O6)) geometrical isomer of the [Cr(eda3p)]- complex ion was prepared and resolved into optical isomers. IR, electronic absorption and CD spectra were used for characterizing the complex. CD data in the region of the d-d transitions are discussed in comparison with those of other edta-type Cr(III) complexes of known configuration. The (-)589-isomer of the trans(O5O6)-[Cr(eda3p)]- complex, having a positive CD peak at lowest energy in the first spin-allowed d-d absorption band region, is tentatively assigned the LAMBDA-configuration.

Ba[Cu(eddadp)]·8H2O is proposed to adopt a trans(O5) geometry (two axial acetates) on the basis of density functional theory calculations and comparisons of IR and UV–vis spectral data. Experimental and computed structural data correlating similar copper(II) chelate complexes have been used to better understand the isomerism and departure from regular octahedral geometry within the series. The in-plane O–Cu–N chelate
