    Description / Table of Contents: Element-Organic Amine/Imine Compounds, XXVIII1). - Polycyclic Phosphorus-Nitrogen Rhenium(I) ComplexesThe thermolysis of [(OC)4RE - NR - P(Cl)(NR2) - NR](2), R = SiMe3 affords the tricyclic phosphorus dispiro compound 3, the cubanelike rhenium complex [Re2(CO)6(μ3-NR)4(μ3 -PNR)2] (4) as well as the tetracyclic rhenium complex 5. The attempt to synthesize 3 from RN-P(NR)(NR2)-NR- P(NR)(NR2 (7), R=SiMe3, and [Re(CO)5X] or [(OC)4ReX]2 (X=Cl, Br), gave the ionic species [RN-(RN)(RHN)P-NR-P- NR-SiMe2-NR]⊕ [Re2(CO)6(μX)3]⊖ (6a, X=Cl; 6b, X=Br). 3, 5, and 6a have been characterized by an X-ray structure analysis.
    Notes: Die Thermolyse von [(OC)4Re-NR -P(Cl)(NR2)-NR] (2), R = SiMe3 ergibt die tricyclische Phosphor-Dispiroverbindung 3, den cubanartigen Rheniumkomplex [Re2(CO)6(μ3-PNR)2] (4) sowie den tetracyclischen Rheniumkomplex 5. Beim Versuch, 3 aus RN-P(NR)(NR2)-NR -P(NR)(NR2) (7), R = SiMe3 und [Re(CO)5X] bzw. [(OC)4ReX]2 (X=Cl, Br) herzustellen, bildeten sich die Komplexsalze [RN- (RN)(RHN)P-NR-SiMe2-NR[⊕ [Re2(CO)6(μX)]⊖ (6a, X = Cl; 6b, X = Br). 3, 5 und 6a wurden durch eine Röntgenstrukturanalyse charakterisiert.
