The coordination chemistry of thiazoline/thiazolidine derivatives. II: synthesis and characterization of [CoCl2(PyTT)] and [ZnCl2(PyTT)] [PyTT=2-(2-pyridyl)imino-N-(2-thiazolin-2-yl)thiazolidine]
摘要:
The compounds dichloro[2-(2-pyridyl)imino-kappaN-N-(2-thiazolin-kappaN-2-yl)thiazolidine]cobalt(II) and dichloro[2-(2-pyridyl)imino-kappaN-N-(2-thiazolin-kappaN-2-yl)thiazolidine]zinc(II) have been isolated and characterized by single crystal X-ray diffraction and IR spectroscopy. Moreover, the cobalt(II) complex has been studied by means of magnetic susceptibility measurements and UV-Vis-NIR diffuse reflectance. Both complexes are isostructural. The environment around the cobalt(II) and zinc(II) atoms may be described as a distorted tetrahedral geometry with the metallic atoms coordinated to two chlorine atoms [Co-Cl(1) = 2.241(1) Angstrom: Co-Cl(2) = 2,2210) Angstrom]. [Zn-Cl(1) = 2.235(1) Angstrom: Zn-Cl(2) = 2.211(1) Angstrom]. one thiazoline nitrogen [Co-N(1) = 1.982(2) Angstrom], [Zn-N(1) = 2.021(2) Angstrom] and one imino nitrogen [Co-N(3) = 2.009(1) Angstrom], [Zn-N(3) = 2.056(2) Angstrom].
