Synthesis, Characterization and X-ray Crystal Structures of New Ethylxanthato Complexes of Zinc(II) with N-donor Ligands

Zn(II) complexes of general formula [Zn(S2COEt)2L] [L=pyrazole (Hpz) 1; 3,5-dimethylpyrazole (Hdmpz) 2; 2-pyridylamine (pyam) 3; phenyl 2-pyridylamine (phpyam) 4; 2,2'-dipyridylamine (dpyam) 5; 1,4-pyrazine (pyr) 6] have been synthesized and characterized by elemental analyses and IR and NMR spectroscopy. The crystal structures of complexes 2, 5 and 6 have been determined by X-ray diffraction, showing different geometries and modes of coordination of the xanthate ligand depending on the type of N-donor ligand.Peer reviewe
