Summary

Poly(5-vinylsalicylidene-2-benzothiazoline) homopolymer (PVSBH2) and polymer complexes of 5-vinylsalicylidene-2-benzothiazoline with a number of divalent transition metals have been prepared and characterized using spectral (1H NMR and13C-NMR, IR, UV-VIS) and magnetic measurements. The data suggest that the Co(II), Ni(II), Fe(II) and Mn(II) polymer complexes are octahedral dimers, while the rest are monomeric with square planar tetrahedral geometries.

Zusammenfassung

Es wurden homopolymere Poly(5-vinylsalicyliden-2-benzothiazolin)-(PVSBH2) und polymere 5-Vinylsalicyliden-2-benzothiazolin-Komplexe mit einer Reihe von zweiwertigen Metallen hergestellt und mittels spektroskopischer (1H- und13C-NMR, IR, UV-VIS) und magnetischer Messungen charakterisiert. Die Daten erlauben den Schluß, daß es sich bei den Co(II)-, Ni(II)-, Fe(II)- und Mn(II)-Polymerkomplexen um oktahedrale Dimere handelt, während der Rest monomere Strukturen mit planar-tetrahedraler Geometrie zeigt.
