Crystal structure of N,N'-bis-(diiso-propyl-phosphan-yl)-4-methyl-pyridine-2,6-di-amine.

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