title: Synthesis, characterization and crystal structure of a 2-(diethylaminomethyl)indole ligated dimethyl-aluminium complex.
abstract: The title compound, [Al(CH3)2(C13H17N2)] (systematic name; {2-[(di-ethyl-amino)-meth-yl]indol-1-yl-κ(2) N,N'}di-methyl-aluminium), was prepared by methane elimination from the reaction of 2-(di-ethyl-amino-meth-yl)indole and tri-methyl-aluminium. The complex crystallizes readily from a concentrated toluene solution in high yield. The asymmetric unit contains two crystallographically independent mol-ecules. Each mol-ecule has a four-coordinate aluminium atom that has pseudo-tetra-hedral geometry. C-H⋯π inter-actions link the independent mol-ecules into chains extending along the b-axis direction.
