Dimethyl 6,6′-dicyano-2,2′-bipyridine-3,3′-dicarboxylate
In the title compound, C(16)H(10)N(4)O(4), the two pyridine rings are twisted by 44.41 (2)° and the ester groups form dihedral angles of 48.77 (4) and 45.75 (2)° with the corresponding pyridine rings. The crystal structure is stabilized by inter-molecular C-H⋯O hydrogen bonds and π-π stacking inter-actions between the pyridine rings [centroid-to-centroid distance 3.797 (2) Å].

The asymmetric unit of the title compound, C(12)H(12)N(2), contains two half-mol-ecules related by an inversion center, the planes of their pyridine rings being oriented at a dihedral angle of 69.62 (4)°. In the crystal structure, a π-π contact between the pyridine rings [centroid-centroid distance = 3.895 (3) Å] may stabilize the structure. A weak C-H⋯π inter-action is also found.

In the crystal structure of the title compound, C(12)H(12)N(2), the mol-ecule is twisted around the central C-C bond, with a dihedral angle of 8.32 (5)° between the mean planes of the pyridyl rings. The crystal structure is stabilized by arene stacking inter-actions, with a distance of 3.81 (1) Å between the ring centroids.

The title compound, C(16)H(19)NO(4), the hydrogenated ring adopts a twisted conformation. In the crystal, inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into centrosymmetric R(2) (2)(10) dimers. These dimers are further connected via inter-molecular N-H⋯O hydrogen bonds, forming infinite double chains along [001].
