In the title compound, C 20 H 14 N 2 O 8 Á2C 3 H 7 NO, the essentially planar C 20 H 14 N 2 O 8 molecule is centrosymmetric and is hydrogen bonded via the carboxylic acid H atoms to the aldehyde O atom of the dimethylformamide molecules.
Reaction of pyrazine-2,3-dicarboxylic acid, NaOH, KSCN and Cu(NO 3 ) 2 Á3H 2 O led to the formation of Na 2 K 2 [trans-Cu(C 6 H 2 N 2 O 4 ) 2 ](SCN) 2 Á2H 2 O, in which the Cu II atom, on an inversion centre, is approximately in a square-planar environment. This is a new coordination geometry for co
