• Syntheses by both the isothermal matrix in a solid state and by the usual solution method have been tried for chromium (III) complexes with L- and DL-asparagine, L- and DL-aspartic acid, L- and DL-glutamine, L- and DL-glutamic acid, L- and DL-lysine, and L-ornithine. [Cr(L-aspNH<SUB>2</SUB>)<SUB>3</SUB>]·2H<SUB>2</SUB>O, [Cr(DL-aspNH<SUB>2</SUB>)<SUB>3</SUB>]·3H<SUB>2</SUB>O, (NH<SUB>4</SUB>)<SUB>2</SUB>[Cr(L-asp)<SUB>2</SUB>][Cr(D-asp)<SUB>2</SUB>]·4H<SUB>2</SUB>O, and (+)[Cr(L-lys)<SUB>2</SUB>(NH<SUB>3</SUB>)(H<SUB>2</SUB>O)]Cl·4H<SUB>2</SUB>O were obtained by the matrix method in the solid state, while [Cr(L-aspNH<SUB>2</SUB>)<SUB>3</SUB>]·2H<SUB>2</SUB>O, [Cr(DL-aspNH<SUB>2</SUB>)<SUB>3</SUB>]·2H<SUB>2</SUB>O, and (+)[Cr(L-lys)<SUB>2</SUB>(NH<SUB>3</SUB>)(H<SUB>2</SUB>O)]Cl·4H<SUB>2</SUB>O were prepared by the usual solution method. The preparation of chromium(III) complexes with other amino acids was not successful. A new type of complex of chromium(III) containing terdentate DL-aspartic acid and a new mixed chromium(III) complex containing three different ligands (L-lysine, ammine, and aqua) were prepared.
