## Abstract The crystal structures of six (pyrazinecarbonyl)hydrazone di-substituted benzaldehyde derivatives [N~2~C~4~H~3~CONHN = CHC~6~H~3~XY: X,Y = 2,3-Cl~2~; 2,3-(MeO)~2~; 2,4-F~2~; 2,4-Me~2~; 3-HO—4-MeO; 3-MeO—4-HO] and one tri-substituted benzaldehyde derivative, [N~2~C~4~H~3~CONHN = CHC~6~H~
## Abstract The molecules of the (pyrazinecarbonyl)hydrazones of the heterocyclic aldehydes RCHO with R = pyrrol-2-yl, furan-2-yl, thien-2-yl and pyridin-2-yl corresponding to compounds (**2:** X = NH), (**2:** X = O), (**2:** X = S)and **3**, respectively, are formally rather similar. Despite this
