Summary
The reaction of monochloropentaphenoxycyclotriphosphazene with 3-(aminomethyl)pyridine yields 3-(aminomethyl)pyridylpentaphenoxycyclotriphosphazene (1), a new N-donor ligand with five nitrogen atoms as potential coordination centers. Complex formation with copper(II) nitrate yields compound2 with the general structure Cu(1)2(NO3)2. The X-ray structure analysis shows that the copper ion is coordinated by two nitrogen atoms of the pyridine rings and four oxygen atoms of the unsymmetrical bidentate nitrate groups in aJahn-Teller distorted octahedral arrangement.
Zusammenfassung
Die Reaktion von Monochlorpentaphenoxycyclotriphosphazen mit 3-(Aminomethyl)pyridin ergibt 3-(Aminomethyl)pyridylpentaphenoxycyclotriphosphazen (1), einen neuen N-Donor Liganden mit fünf Strickstoffatomen als potentielle Metallkoordinationszentren. Bei der Umsetzung von1 mit Kupfer(II)nitrat entsteht der Metallkomplex2 mit der Zusammensetzung Cu(1)2(NO3)2. Die durch Röntgenstrukturanalyse ermittelte Molekülstruktur zeigt, daß das Kupferion von zwei Stickstoffatomen der Pyridinringe sowie vier Sauerstoffatomen der unsymmetrisch zweizähnigen NitratgruppenJahn-Teller-verzerrt oktaedrisch umgeben ist.
