2,6-BIS(DIMETHYLAMINO)-3,5-PYRIDINEDICARBALDEHYDE

The title molecule, C11H15N3O2, sits on a crystallographic twofold axi s. This highly substituted pyridine compound has a very distorted pyri dine plane (+/-0.1 Angstrom) with the aldehyde O atoms displaced from the plane by ca 1.0 Angstrom and the dimethylamino groups (planar with in 0.06 Angstrom) tilted away from the pyridine plane by 20.5 (1)degre es. The C1-C2 bond length [1.438(3)Angstrom] is much longer than that normally found in pyridine [1.379 Angstrom; Alien, Kennard, Watson, Br ammer, Orpen and Taylor (1987). J. Chem. Sec. Perkin Trans. 2, pp. S1- S19], as reasonably expected from consideration of steric effects.
