The compounds [Cu(CMP)(Him)].H(2)O}(n) (I) and [Cu(CMP)(crea)H(2)O].3H(2)O (II) were synthesized and characterized by X-ray diffraction, thermal, spectral and magnetic methods (CMP=N-carboxymethyl-;l-prolinato(2-) ion, Him=imidazole and crea=creatinine). Appropriate structural comparison with other compounds such as [Cu(CMP)(H(2)O)].H(2)O}(n), [Cu(crea)(2)Cl(2)] and [Cu(dipeptide)(crea)(H(2)O)(x)]
化合物[Cu(CMP)(Him)]。H(2)O}(n)(I)和[Cu(CMP)(crea)H(2)O] .3H(2)O(II)为通过X射线衍射,热,光谱和磁性方法合成并表征(CMP = N-羧甲基-; 1-prolinato(2-)离子,Him =咪唑,crea =肌酸酐)。与其他化合物,例如[Cu(CMP)(H(2)O).H(2)O}(n),[Cu(crea)(2)Cl(2)]和[Cu(已制成nH(2)O(x = 0或1)来证明crea可以充当咪唑样配体(因为它是二肽)(crea)(H(2)O)(x)]。nH(2)O(x = 0或1)能够促进铜(II)络合物中相同的CMP到CMP三齿构象变化,以及讨论控制'Cu(CMP)络合物-crea分子识别过程的配体相互作用。与相关三元复合物中发现的相反,我们已经得出结论,由于这些配体的供体和/或受体H键性质之间的不适当对应,Cu-CMP-cre
