摘要

对镍(II)离子与组氨酸(His)和半胱氨酸(Cys)的混合配体配合物在298 K、离子强度为0.5 mol·dm−3 (KNO3)的水溶液中进行了电位和量热研究。利用络合物形成热力学参数的比较分析，讨论了三元络合物中氨基酸残基可能的配位模式。

Mixed-Ligand Nickel(II) Complexes with Histidine and Cysteine in Aqueous Solution: Thermodynamic Approach

Potentiometric and calorimetric study on mixed-ligand complexes of nickel(II) ion with histidine (His) and cysteine (Cys) has been carried out in aqueous solution at 298 K and the ionic strength of I = 0.5 mol·dm⁻³ (KNO₃). Possible coordination modes of amino acid residues in ternary complexes are discussed using comparative analysis of thermodynamic parameters of complex formation.

期刊介绍： Journal of Solution Chemistry offers a forum for research on the physical chemistry of liquid solutions in such fields as physical chemistry, chemical physics, molecular biology, statistical mechanics, biochemistry, and biophysics. The emphasis is on papers in which the solvent plays a dominant rather than incidental role. Featured topics include experimental investigations of the dielectric, spectroscopic, thermodynamic, transport, or relaxation properties of both electrolytes and nonelectrolytes in liquid solutions.
