Anorganische Und Physikalische Chemie


Template condensation of α-diketones such as 2,3-butanedione or benzil with 1,8-diamino-3,6-diazaoctane in the presence of Cr(III), Fe(III) and Co(II) results in the formation of macrocyclic complexes of the type [MLX2]X and [CoLX]X (where M=Cr(III), Fe(III), L=N4 macrocycle and X=NO 3 or Cl). The complexes have been characterized by elemental analyses, conductance and magnetic measurements, molecular weight determinations, infrared and diffuse reflectance spectral studies.

Cr(III)-, Fe(III)- und Co(II)-Komplexe mit Tetraazamacrocyclen aus 2,3-Butandion oder Benzil und 1,8-Diamino-3,6-diazaoctan


Kondensation von α-Diketonenen wie 2,3-Butandion oder Benzil mit 1,8-Diamino-3,6-diazaoctan in Gegenwart von Cr(III), Fe(III) und Co(II) resultiert in der Bildung von macrocyclischen Komplexen vom Typ [MLX2]X und [CoLX]X mit M=Cr(III), Fe(III), L=N4-Macrocyclus und X=NO 3 oder Cl. Die Komplexe wurden mittels Elementaranalyse, Leitfähigkeits-und magnetischen Messungen, Molekulargewichtsbestimmung und Infrarot- bzw. diffuser Reflexions-Spektren charakterisiert.
