N′-(Adamantan-2-ylidene)thiophene-2-carbohydrazide

Abstract

In the title molecule, C15H18N2OS, a small twist is noted, with the dihedral angle between the central carbohydrazone residue (r.m.s. deviation = 0.029 Å) and the thio-phene ring being 12.47 (10)°. The syn arrangement of the amide H and carbonyl O atoms allows for the formation of centrosymmetric dimers via N - H⋯O hydrogen bonds. These are linked in the three-dimensional structure by C - H⋯π interactions. The thio-phene ring is disordered over two co-planar orientations, the major component having a site-occupancy factor of 0.833 (2). © Kadi et al. 2011.
