✦ Synopsis

In the title complex, 2C 9 H 10 O 4 ÁC 8 H 12 N 2 , there is an inversion centre at the centre of the 2,3,5,6-tetramethylpyrazine molecule, which is linked to two endo-norbornene-cis-5,6-dicarboxylic acid molecules via O-HÁ Á ÁN hydrogen bonds. In the crystal structure, O-HÁ Á ÁO and O-HÁ Á ÁN hydrogen bonds propagate a one-dimensional zigzag chain, which is extended into layers when combined with longer C-HÁ Á ÁO hydrogen bonds.

In the title compound, C 10 H 16 O 5 , the carboxylate group at the C-2 position is axial, but that at C-5 is equatorial. These carboxylate groups form hydrogen-bonded rings [average OÁ Á ÁO H distance = 2.64 (1) A Ê ] across the inversion centers at ( 1 2 , 0, 0) and ( 1 2 , 1 2 , 1 2 ), respective
