P—H-functionalised Phosphanido Ligands in Transition Metal Chemistry: Molecular Structure of CpZr(μ-PHtBu)2(μ-PtBu)2 {Zr(μ-Cl)Cp}2The reaction of polymeric [CpZrCl3]n with solvent-free LiPHtBu yields the trinuclear ZrIII/ZrIV complex CpZr(μ-PHtBu)2(μ-PtBu)2 {Zr(μ-Cl)Cp}2 (1) in a redox reaction in low yield. The oxidation product (PHtBu)2 is observed by 31P-NMR spectroscopy. 1 crystallises tetragonal in the space group P43212 with a = 1130.5(5) pm and c = 3415.7(5) pm.
Notes:
Die Reaktion von polymerem [CpZrCl3]n mit solvatfreiem LiPHtBu liefert in einer Redoxreaktion den dreikernigen ZrIII/ZrIV-Komplex CpZr(μ-PHtBu)2(μ-PtBu)2{Zr(μ-Cl)Cp}2 (1) in geringer Ausbeute. 31P-NMR-spektroskopisch kann die Bildung des Oxidationsprodukts (PHtBu)2 gezeigt werden. 1 kristallisiert tetragonal in der Raumgruppe P43212 mit a = 1130,5(5) pm und c = 3415,7(5) pm.
