Thermodynamic considerations in co-ordination. Part XVIII. Formation constants for cadmium(II)–amino-acid complexes as determined by glass and solid-state cadmium-electrode potentiometry

A number of Pd(II) and Pt(II) complexes of amino acids and dipeptides have been isolated and characterized. The solution and solid-state circular dichroism of the amino acid complexes show a fairly consistent pattern, which is opposite to that shown by the dipeptide complexes. Some of the problems associated with the interpretation of the spectra in terms of spectroscopic assignment and structural features are discussed.

Amino Acid Complexes

Complex amino acid complexes of manganese ions were synthesized using the chelation technology under microwave irradiation. The influences of amount of water, reaction time, microwave power and the molar ration of complex amino acid and manganese on the yield of the synthesized compounds were investigated. Results suggest that optimal synthesis conditions are amount of water, 4 mL, irradiation time, 4 min, microwave power, 500 W, and the molar ration of reactant, 2:1, and the yield of the synthesized compounds was 67.42%.

Covalent Interactions

The reaction of palladium(II) acetate with acyclic amino acids in acetone/water yields square planar bis-chelated palladium amino acid complexes that exhibit interesting non-covalent interactions. In all cases, complexes were examined by multiple spectroscopic techniques, especially HRMS (high resolution mass spectrometry), IR (infrared spectroscopy), and 1H NMR (nuclear magnetic resonance) spectroscopy. In some cases, suitable crystals for single crystal X-ray diffraction were able to be grown and the molecular structure was obtained. The molecular geometries of the products are discussed. Except for the alanine complex, all complexes incorporate water molecules into the extended lattice and exhibit N-H···O and/or O···(HOH)···O hydrogen bonding interactions. The non-covalent interactions are discussed in terms of the extended lattice structures exhibited by the structures.
