Li5Pt2H9, ein komplexes Hydrid mit isolierten [Pt2H9]5−‐Ionen

Abstract: 9] Fur eine [4 + 21-Cycloaddition mu0 sich eine Butadieneinheit in s-cis-Konformation befinden, die Konforination der anderen kann gleichemaDen s-cis oder s-trans sein. Liegen beide Reaktionspartner in s-trans-Konformation vor, muOte eine [2 + 2]-Cyclodddition stattfinden. Ein entsprechendes Produkt ist allerdings nicht nachweisbar, weshalb wir davon ausgehen, dab 1 im Grundzustand in der s-cis-Konformation vorliegt. Der Einfachheit hdlber nehmen wir diese als die einzige reaktive Konformation an, obgleich die… Show more

“…The D‐Ni‐D bond angles deviate from the ideal tetrahedral angle of 109° (terminal: D‐Ni‐D 92–129°, bridging: Ni1‐D13‐Ni3 157°, Ni1‐D12‐Ni3 127°, Ni2‐D23‐Ni4 125°). In particular, the Ni2D23Ni4 bridge in I is significantly opened, but much less so than the linear PtHPt bridge found in the dinuclear [Pt 2 H 9 ] 5− complex of Li 5 Pt 2 H 9 2…”

“…Polynuclear hydride complexes with bridging hydride ligands are less common, but are of considerable interest because of possible links to interstitial hydrides. An example involving a 5d metal is the dinuclear [Pt 2 H 9 ] 5− complex anion in Li 5 Pt 2 H 9 , which contains a linear PtHPt bond 2. No examples of polynuclear solid‐state complexes involving 3d metals have yet been reported.…”
