Darstellung und Eigenschaften gemischter Fluoro‐Halogeno‐Komplexe von Osmium(IV)

Abstract: Die Darstellung von [OsF5Cl]2−, cis‐ und trans‐[OsF4Cl3]2−,[OsF4Cl3]2− trans‐ [OsF3Cl4]2− und trans‐[OsF4ClBr]2− wird beschrieben. Die neuen Gemischtligandkomplexe werden durch ihre Schwingungs‐ und Absorptionsspektren, chemische Reaktionen in Lösung und in festem Zustand sowie durch röntgenographische Untersuchungen charakterisiert. Der Einfluß der Symmetrie, des trans‐Effekts und der Donorwirkung der verschiedenen Halogenide auf die kinetische Stabilität der Komplexe wird diskutiert.

“…A more common type of oxidative ligand exchange is the preparation of fluoro-mixed complexes utilizing BrF 3 . The postulated stereospecific formation of fac -K 2 [PtF 3 Cl 3 ] as the sole oxidation product of K 2 [PtCl 6 ] with BrF 3 has never been verified. , Depending on the reaction conditions, other mixed species [PtF n Cl 6 - n ] 2- have been detected; however, for n = 2, 3, 4, only the cis/fac isomers have been present . Corresponding fluorochloro complexes are known for Re(IV,V), Os(IV,V), and Ir(IV,V). Octahedral complexes containing the heavier halides, Br or I, together with F are rare, but are known for Pt(IV) and Os(IV), ,, and most notably Re(IV), for which there are many examples of 3-fold mixed species …”

“…Zwar ist der Nachweis aller G lieder der Reihe [WF"C16_"] und vieler F-haltiger Spezies von Sn(IV) durch NM R-M essungen in Gleichgewichtslösungen bereits vor längerer Zeit geführt worden [5,6], die Isolie rung reiner Verbindungen beschränkt sich aber auf einzelne kinetisch stabile Fluorohalogenokom plexe der schwereren Platinelem ente [7][8][9], Von diesen sind durch Ligandensubstitution in organischen Solventien jedoch nur die niedrig fluorierten Spezies zu gänglich [10,11].…”
