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

Project description: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).

N'-[(1E)-(4-Fluoro-phen-yl)methyl-idene]thio-phene-2-carbohydrazide.

Project description:In the title compound, C(12)H(9)FN(2)OS, the thienyl ring is disordered over two positions, with the S atom of the major component [occupancy = 87.08?(16)°] oriented towards the ortho-H atom of the benzene ring.
