Crystal structure of N,N,N′,N′-tetra­methyl­ethane­di­amine

The title compound N,N,N′,N′-tetra­methyl­ethanedi­amine, C(6)H(16)N(2), is a bidentate amine ligand commonly used in organolithium chemistry for deaggregation. Crystals were grown at 243 K from n-pentane solution. The complete mol­ecule is generated by a crystallographic center of symmetry and the conformation of the di­amine is anti­periplanar. To investigate the inter­molecular inter­actions, a Hirshfeld surface analysis was performed. It showed that H⋯H (van der Waals) inter­actions dominate with a contact percentage of 92.3%.
