Abstract: Abstract A new pyrazine compound, has been synthesised and characterised by single-crystal X-ray diffraction: monoclinic, P21/c with a = 11.0707(3) Å, b = 5.23700(10) Å, c = 16.6997(5) Å, ß = 103.5385(16)°, Mr = 376.40, V = 941.30(4) Å3, Z = 2. Each molecule possesses C i symmetry with the two halves of the molecule related by an inversion centre. C–H···p and C=O···p interactions held the molecules together.

Marques, Manuela Ramos Silva, Ana Matos Beja, Abílio J. F. N. Sobrala In dibenzyl-3,6-dimethylpyrazine-2,5-dicarboxylate, each molecule possesses C i symmetry. The molecules are assembled in chains via carbonyl···p interactions.
