Abstract

The title compound N,N,N',N'-tetra-methyl-ethanedi-amine, C₆H₁₆N₂, is a bidentate amine ligand commonly used in organolithium chemistry for deaggregation. Crystals were grown at 243 K from n-pentane solution. The complete mol-ecule is generated by a crystallographic center of symmetry and the conformation of the di-amine is anti-periplanar. To investigate the inter-molecular inter-actions, a Hirshfeld surface analysis was performed. It showed that H⋯H (van der Waals) inter-actions dominate with a contact percentage of 92.3%.

Keywords: Hirshfeld surface analysis; bidentate ligand; crystal structure.
