Intermolecular interactions and packing effect in the cis-1,2,3,6-tetrahydrophtalic anhydride crystalline structure
Written by sctunisie no commentsThe investigation of the environment around each formular group in the unit cell of the cis-1,2,3,6-tetrahydrophthalic anhydride crystalline structure provides evidence for the existence of molecular arrangements favorising specific nucleophile-electrophile intermolecular interactions between oxygen and carbonyl carbon atoms. The analysis in terms of geometrical criterions shows that the main interactions, essentially, of dipole-dipole type, appear to be between the local electric dipoles of carbonyl groups. The study of the influence of these interactions on packing effects allows us to justify the differences observed between the structures of formular groups in the unit cell.
