ABSTRACT
In the title compound, C(14)H(12)N(2)O(2), the asymmetric unit comprises one half-mol-ecule with an inversion center between the pyridine rings. The rings are trans coplanar with the acetyl groups deviating slightly from the mean planes, making a dihedral angle of 4.63â (4)°. In the crystal, mol-ecules are linked by weak inter-molecular C-Hâ¯O hydrogen bonds, forming a supra-molecular sheet parallel to (100).
