Complexes of Zn(II) and Сu(II) with the Amino Derivatives of Deoxycholic Acid: Syntheses, Structures, and Properties
Complexes [Zn(L)Cl2] (I), Cu(L)Cl2 ∙ H2O (II), Zn(L1)Cl2 ∙ 0.5H2O (III), and Cu(L1)Cl2 ∙ 0.5H2O (IV) (where L and L1 are the diaminopropylene and diaminoethylene derivatives of deoxycholic acid, respectively) are synthesized. The structure of mononuclear complex I is determined by X-ray structure analysis (CIF file CCDC no. 1875305). The coordination polyhedron of the Zn atom (Cl2N2) is a distorted tetrahedron. According to the X-ray diffraction data, the crystals of compounds III and IV are isostructural. It is shown by IR spectroscopy that the structures of complexes II–IV are similar to that of complex I. In the solid phase, compounds L and L1 possess photoluminescence in the visible spectral range (λmax = 440 and 415 nm, respectively). Complex formation with Zn2+ ions does not change the photoluminescence properties of L and L1.
