Crystal structure of 2,5-bis­(4-methyl­pyridin-2-yl)pyrazine chloro­form disolvate

The heterocyclic molecule in the title solvate, C₁₆H₁₄N₄·2CHCl₃, possesses inversion symmetry, with the inversion centre situated at the centre of the pyrazine ring. The outer pyridine rings are inclined to the central pyrazine ring by 4.89 (9)°. The compound crystallized as a chloro­form disolvate with the solvent mol­ecules linked to the title mol­ecule by C—H...N hydrogen bonds. In the crystal, mol­ecules are further linked by π–π inter­actions involving the pyrazine and pyridine rings of neighbouring mol­ecules [inter-centroid distance = 3.5629 (12) Å; symmetry code: x, y + 1, z + 1].
