title: Crystal structure of 4,4'-dimeth-oxy-2,2'-bi-pyridine.
abstract: In the title compound, C12H12N2O2, the dihedral angle between the planes of the two pyridine rings is 5.8 (1)°. Neighbouring mol-ecules are linked via C(Me)-H⋯N inter-actions, generating a two-dimensional sheet structure; C-H⋯π inter-actions further link the mol-ecules into a three-dimensional network. An overlapped arrangement of parallel pyridine rings in neighbouring mol-ecules [centroid-to-centroid distance = 3.6655 (15) Å] is observed in the crystal structure.
