Intramolekular stabilisierte Übergangsmetallamide: 2‐(Dimethylaminomethyl)pyrrolyl‐Komplexe des Titan(III), Vanadium(III), Chrom(III), Cobalt(II) und Nickel(II)

Intramolecularly Stabilized Metal Amides: 2‐(Dimethylaminomethyl)pyrrolyl Complexes of Titanium(III), Vanadium(III), Chromium(III), Cobalt(II) and Nickel(II) By the metallation of 2‐(dimethylaminomethyl)pyrrol (HL) with butyllithium the lithium pyrrolide LiL (1) was obtained. The reactions of 1 with TiBr3 · 3 THF, VBr3 · 3 THF, CrBr3 · 3 THF, CoBr2 · 2 THF, and NiBr2 · 1.67 THF result in the formation of the 2‐(dimethylaminomethyl)pyrrolyl complexes of type ML3 (2–4), and ML2 (5, 6), respectively. The structures of these new compounds are discussed on the basis of magnetic and visible absorption measurements. An X‐ray crystal structure determination of 4 reveals a strongly distorted octahedral environment of the chromium atom with facial arrangement of the ligands.
