The crystal structures and Hirshfeld surface analysis of N′,N′′′-((1E,1′E)-{[methylenebis(oxy)]bis(6-bromo-3,1-phenylene)}bis(methanylylidene))bis(isonicotinohydrazide) dihydrate and N′,N′′′-((1E,1′E)-{[butane-1,4-diylbis(oxy)]bis(2,1-phenylene)}bis(methanylylidene))bis(isonicotinohydrazide) [+ solvent]

The title compounds, C27H20Br2N6O4·2H2O, (I), and C30H28N6O4·[+ solvent], (II), both crystallize with one half-molecule in the asymmetric unit. The whole molecule of (I) is generated by twofold rotation symmetry, with the twofold rotation axis bisecting the C atom of the –O—CH2—O– bridge. This resul...
