Ternary copper(II) complexes with N-carboxymethyl-l-prolinato(2-) ion and imidazole or creatinine: a comparative study of the interligand interactions influencing the molecular recognition and stability.

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).
