Artykuł
The new five-coordination zinc(II) complex of formula [Zn(Im)(l-tyr)2]2·5H2O consisting of l-tyrosine (l-tyr) and imidazole (Im) molecules as ligands was prepared as crystals and characterized by X-ray diffraction, IR-FIR vibrational and UV–Vis electronic spectroscopy. The [Zn(Im)(l-tyr)2]2·5H2O complex crystallizes in the orthorhombic crystal system and P21212 space group. The [ZnN2N′O2] chromophore has distorted bipiramidal geometry with value of τ parameter 0.7. The sensitive intra and inter-molecular hydrogen bonds created the layers arrangement and the “pseudo-baskets” fashion. The intraligand charge transfer (ILCT) π–π∗ and π–π∗ transitions in the ligands molecule are corresponded to the intensity bands in the UV–Vis region.
