1-(2-Pyridyl)ethan-1-one 8-quinolylhydrazone and 1-(1H-pyrrol-2-yl)ethan-1-one 8-quinolylhydrazone

D. E. Lynch and I. McClenaghan

Abstract: The structures of the title compounds, C₁₆H₁₄N₄, (I), and C₁₅H₁₄N₄, (II), respectively, have been determined, and their molecular packing arrangements compared. Both are essentially flat molecules, with respective dihedral angles between the quinoline and heterocyclic rings of 19.0 (1) and 8.5 (2)°. The pyridyl derivative, (I), packs in a P2₁/c unit cell, while in the pyrrolyl compound, (II), the molecules pack in Pca2₁ and form a crinkled ribbon arrangement through the association of pyrrole NH groups with the quinoline N atoms.

Formula: C₁₆H₁₄N₄ and C₁₅H₁₄N₄
