Crystal structure of N,N'-bis­(diiso­propyl­phosphan­yl)-4-methyl­pyridine-2,6-di­amine

In the mol­ecule of the title compound, C₁₈H₃₅N₃P₂, the methyl­pyridine-2,6-di­amine moiety is almost planar, with a maximum deviation of 0.0129 (9) Å for one of the amine N atoms. Whereas one of the P atoms is co-planar with this mean plane [deviation = 0.0158 (10) Å], the other P atom is considerably displaced out of the mean plane by 0.5882 (10) Å. In the crystal, no directional intermolecular interactions beyond van der Waals contacts could be identified.
