Crystal structure of 2,5-bis-(4-methyl-pyridin-2-yl)pyrazine chloro-form 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 chloro-form disolvate with the solvent mol-ecules linked to the title mol-ecule by C-H⋯N hydrogen bonds. In the crystal, mol-ecules are further linked by π-π inter-actions involving the pyrazine and pyridine rings of neighbouring mol-ecules [inter-centroid distance = 3.5629 (12) Å; symmetry code: x, y + 1, z + 1].
