    Description / Table of Contents: Polymeric (Dihydrodibenzo[b,i]-1,4,8,11-tetraazal[14]annulene)iron(II) with Pyrazine Bridges5,14-Dihydrodibenzo[b,i][1,4,8,11]tetraazacyclotetradecin (H2taa) (3) and ferrous acetate reacts in the presence of pyridine via the pyridine complex 4 to form Fetaa (5). If 5 is reacted with pyrazine under various conditions, the pyrazine bridged polymer 6 is formed as the only product. The instable monomer 7 could not be isolated. The polymer 6 shows a conductivity of 1·10-5 S·cm-1 at room temperature which is 107 times higher than that of 5.
    Notes: 5,14-Dihydrodibenzo[b,i][1,4,8,11]tetraazacyclotetradecin (H2taa) (3) reagiert mit Eisen(II)-acetat in Gegenwart von Pyridin über den Pyridinkomplex 4 zu Fetaa (5). Mit Pyrazin entsteht aus 5 unter verschiedenen Bedingungen nur das Pyrazin-überbrückte Polymere 6, während das instabile Monomere 7 nicht isoliert werden kann. Gegenüber 5 zeigt das Polymere 6 mit 1·10-5 S·cm-1 eine um 107 erhöhte Dunkelleitfähigkeit bei Raumtemperatur.
