N-Salicylideneamino acid complexes of Chromium(III), K[Cr(sal:aa)2]·nH2O (n=2, aa=glycine, DL- serine, DL- or L-methionine; n=1, aa=DL- or L- leucine, DL- or L-phenylalanine, DL-tryptophan; n=0, aa=α-DL-alanine) were prepared and characterized. The conductivity values (∼80 ohm-1 cm2 mol-1) in methanol inferred a 1:1 electrolyte nature of the complexes. TG data indicated that the end residue is a mixture of K2CO3 and Cr203. The octahedral geometry around chromium(III) was suggested from the magnetic and UVVis spectral data. The absolute configuration of the complexes is assigned as δ from the CD spectra. The dibasic tridenticity of the ligand was inferred from the IR and far-IR spectral studies. An octahedral geometry around chromium(III) is completed by the two tridentate Schiff base chelates. © 1987.
