title: N-(6-{2-[6-(2,2-Dimethyl-propanamido)-2-pyrid-yl]eth-yl}-2-pyrid-yl)-2,2-dimethyl-propanamide.
abstract: The title compound, C(22)H(30)N(4)O(2), lies about a crystallographic inversion center. The whole mol-ecule is disordered over two positions with a refined occupancy ratio of 0.636 (10):0.364 (10). The pyridine rings are approximately planar, with maximum deviations of 0.033 (10) and 0.063 (17) Å for the major and minor components, respectively. The mean planes of the pyridine rings form dihedral angles of 17 (2)° in the major component and 18 (2)° in the minor component with the respective formamide groups attached to them. In the crystal packing, inter-molecular N-H⋯O and C-H⋯O hydrogen bonds link the mol-ecules into two-dimensional networks parallel to the ab plane.
