Abstract
Two crystal structures of EuIII complexes with CDTA (trans-1,2-diaminocyclohexane-N,N,N′,N′-tetraacetate), [C(NH2)3]3[Eu2(CDTA)2(H2O)2]ClO4 · 7H2O (I) and [C(NH2)3][Eu(CDTA)(H2O)] · 2.375H2O (II), are presented. Both structures are polymeric and the central metal ions are eight-coordinate. The first coordination sphere of each EuIII cation contains five carboxylate oxygen atoms, two nitrogen ones and a water molecule. For I, as well as for water solutions of the EuIII–CDTA complex at various pH values, the spectroscopic (UV–Vis) properties were investigated.
