    Description / Table of Contents: Transition Metal Complexes of 1,1,3,3-Tetrakis(dimethylamino)-1λ5,3λ5-Diphosphete1,1,3,3-Tetrakis(dimethylamino)-1λ5,3aλ5-diphosphete, 1, reacts with W(CO)6 to yield the isomeric complexes {1,1,3,3-tetrakis(dimethylamino)-1λ5,3λ5-diphosphete}(pentacarbonyl)tungsten 4 and {1,1,3,3-tetrakis(dimethylamino)-1,4-dihydro-1λ5,3λ5-[1,3]diphosphetium}(pentacarbonyl)tungsten 5. With Cr(CO)6 the complex {1,1,3,3-tetrakis(dimethylamino)-1λ5,3λ5-diphosphete}(pentacarbonyl)chromium 6 is formed. From the reaction products of Fe3(CO)12 and Fe2(CO)9 with 1 the complex {1,1,3,3-tetrakis(dimethylamino)-1λ5,3λ5-diphosphete}(pentacarbonyl)iron 7 could be isolated. Properties, nmr, ir and mass spectra of the new compounds are reported. 6 and 7 were characterized by X-ray structure determinations.
    Notes: 1,1,3,3-Tetrakis(dimethylamino)-1λ5,3λ5-diphosphet, 1, reagiert mit W(CO)6 zu den isomeren Komplexen {1,1,3,3-Tetrakis(dimethylamino)-1λ5,3λ5-diphosphet}(pentacarbonyl)wolfram 4 und {1,1,3,3-Tetrakis(dimethylamino)-1,4-dihydro-1λ5,3λ5-[1,3]diphosphetium}(pentacarbonyl)wolfram 5, mit Cr(CO)6 zu dem Komplex {1,1,3,3-Tetrakis(dimethylamino)-1λ5,3λ5-diphosphet}(pentacarbonyl)chrom 6. Aus den Reaktionsprodukten von Fe3(CO)12 und Fe2(CO)9 mit 1 konnte der Komplex {1,1,3,3-Tetrakis(dimethylamino)-1λ5,3λ5-diphosphet}(pentacarbonyl)eisen 7 isoliert werden. Eigenschaften, NMR-, IR- und Massenspektren der neuen Verbindungen werden mitgeteilt. 6 und 7 wurden zusätzlich durch Kristallstrukturanalysen charakterisiert.
