Metal Alkyl and Aryl Compounds, XX: Preparation and Crystal Structure of Dimeric Phenyllithium · N, N, N′, N′-Tetramethylethylenediamine, Bis[μ-phenyl-(N, N, N′, N′-tetramethylethylenediamine)lithium]The adduct phenyllithium · N, N, N′, N′-tetramethylethylenediamine has been prepared and its crystal structure determined by X-ray methods (R = 0.066, 1595 significant reflections). The monoclinic unit cell (space group C2/c) contains 4 molecules of a dimer. Similar to dimeric triphenylaluminium in each molecule two Li atoms are linked by two phenyl bridging groups. By the addition of one diamine ligand each Li atom obtains fourfold coordination.
Notes:
Das Addukt Phenyllithium · N, N, N′, N′-Tetramethylethylendiamin wurde dargestellt und seine Kristallstruktur röntgenographisch ermittelt (R = 0.066, 1595 signifikante Reflexe). Die monokline Elementarzelle (Raumgruppe C2/c) enthält 4 Moleküle eines Dimeren. Ähnlich wie im dimeren Triphenylaluminium sind in jedem Molekül zwei Li-Atome durch zwei Phenyl-Gruppen verbrückt. Durch die Anlagerung eines Diamin-Liganden erreicht jedes Li-Atom vierfache Koordination.
