4-Methylpyridine (C6H7N) has been studied at 120 K by combined x-ray and neutron diffraction. It crystallizes in the space group I41a: a=7.618(5) A(ring), c=18.635(10) A(ring), and Z=8. The crystal structure was solved by direct methods and refined to RF =0.059 (x-ray data) and RF =0.035 (neutron data), respectively, after reducing the intensities of the meroedrically twinned crystals. The resulting X–N synthesis agrees well with the theoretically calculated (4-31G+BF) dynamic electron deformation density.
