3,5-Bis[(dimethylamino)methyl]-1-nitro-4-(trimethylsilyl)benzene

Abstract

The title compound, C15H27N3O2Si, which is an NCN {NCN = 2,6-bis[(dimethylamino)methyl]phenyl} pincer ligand, nitro-substituted in the para position, features intramolecular C—H...N and intermolecular C—H...O hydrogen-bond contacts producing dimeric units. The Si atoms are essentially tetrahedral with normal bond lengths and angles. The nitro groups are in the planes of the corresponding benzene rings and the amino groups are mutually trans. Despite the presence of four independent molecules in the asymmetric unit, all of which have essentially the same geometry, there is no pseudo-translational symmetry present.
