N'-(Adamantan-2-yl-idene)thio-phene-2-carbohydrazide.

ABSTRACT: In the title mol-ecule, C(15)H(18)N(2)OS, 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?? inter-actions. The thio-phene ring is disordered over two co-planar orientations, the major component having a site-occupancy factor of 0.833?(2).

In the title mol-ecule, C(15)H(18)N(2)OS, 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 inter-actions. The thio-phene ring is disordered over two co-planar orientations, the major component  ...[more]
