Imidazole Derivatives. XXII. Imidazoliniminato Complexes of Titanium. Syntheses and X-Ray Structures of [ImNTiCl3]2 and [ImNTiCl3 · 2 MeCN] (ImN = 1,3-Imidazolin-2-imino)1,3-Dimethyl-2-trimethylsilyliminoimidazoline(ImNSiMe3, 7) reacts with TiCl4 in n-pentane to give the dinuclear complex [(ImN)TiCl3]2 (8) which is transferred into the mononuclear compound (ImN)TiCl3 · 2 MeCN (9) on treatment with acetonitrile. The X-ray structure analyses demonstrate the strong donor ability of the imidazoliniminato substituent both in the terminal and bridging coordination mode similar to that of the phosphaniminato group R3PN.
Notes:
1,3-Dimethyl-2trimethylsilyliminoimidazolin(ImNSiMe3, 7) reagiert mit TiCl4 in n-Pentan zum Zweikernkomplex[(ImN)TiCl3]2 (8), der durch Acetonitril in die einkernige Verbindung [(ImN)TiCl3 · 2 MeCN] (9) überführt wird. Die Kristallstrukturanalyse zeigt die starken Donoreigenschaften der Imidazoliniminato-Gruppe ImN in verbrückender wie endständiger Koordination vergleichbar der des Phosphaniminato-Liganden R3PN.
