Crystal Structure and Hirshfeld Surface Analysis of Acetoacetanilide Based Reaction Products [PDF]

Molecules, 2020
We report an unprecedented multicomponent reaction of acetoacetanilide with malononitrile leading to a structurally novel bicyclic product (9) in a high yield. The structure has been confirmed by X-ray crystallography and comparative Hirshfeld surface analysis of 5-cyano-2-hydroxy-2-methyl-N-phenyl-4-(yridine-4-yl)-6-(thiophen-2-yl)-3,4-dihydro-2H ...

Crystal structure and Hirshfeld surface analysis of 4-bromoanilinium nitrate [PDF]

Acta Crystallographica Section E Crystallographic Communications, 2020
The title compound C4H7BrN+·NO3 − crystallizes in the monoclinic crystal system with space group P21/c. In the crystal, π-π stacking interactions and strong N—H...O and C—H...O hydrogen bonds link the cations and anions into layers parallel to the bc plane. The O...H/H...O interactions between the cation and anion are the major factor
