Crystal structure of S-octyl (E)-3-(4-meth-oxy-benzyl-idene)di-thio-carbazate.

ABSTRACT: As already observed in similar mol-ecules, the di-thio-carbazate group in the title compound, C17H26N2OS2, adopts an EE configuration with respect to the C=N bond of the benzyl-idene moiety. In the crystal, mol-ecules are connected into inversion dimers by pairs of N-H?S hydrogen bonds. The dimers are linked by weak ?-? inter-actions, with centroid-to-centroid distances of 3.723?(11)?Å, forming chains parallel to [110].

Crystal structure of benzyl (E)-2-(3,4-di-meth-oxy-benzyl-idene)hydrazine-1-carbodi-thio-ate.

Project description:The title compound, C17H18N2O2S2, synthesized via a condensation reaction between S-benzyl di-thio-carbazate and 3,4-di-meth-oxy-benzaldehyde, crystallized with two independent mol-ecules (A and B) in the asymmetric unit. Both mol-ecules have an L-shape but differ in the orientation of the benzyl ring with respect to the 3,4-di-meth-oxy-benzyl-idine ring, this dihedral angle is 65.59?(8)° in mol-ecule A and 73.10?(8)° in mol-ecule B. In the crystal, the A and B mol-ecules are linked via pairs of N-H?S hydrogen bonds, forming dimers with an R 2 (2)(8) ring motif. The dimers are linked via pairs of C-H?O hydrogen bonds, giving inversion dimers of dimers. These units are linked by C-H?? inter-actions, forming ribbons propagating in the [100] direction.

S-Benzyl 3-[1-(6-methyl-pyridin-2-yl)ethyl-idene]di-thio-carbazate: crystal structure and Hirshfeld surface analysis.

Project description:In the title di-thio-carbazate ester, C16H17N3S2 (systematic name: (Z)-{[(benzyl-sulfan-yl)methane-thio-yl]amino}[1-(6-methyl-pyridin-2-yl)ethyl-idene]amine), the central methyl-idenehydrazinecarbodi-thio-ate (C2N2S2) core is almost planar (r.m.s. deviation = 0.0111 Å) and forms dihedral angles of 71.67 (3)° with the approximately orthogonally inclined thio-ester phenyl ring, and 7.16 (7)° with the approximately coplanar substituted pyridyl ring. The latter arrangement and the Z configuration about the imine-C=N bond allows for the formation of an intra-molecular hydrazine-N-H⋯N(pyrid-yl) hydrogen bond that closes an S(6) loop. In the crystal, phenyl-C-H⋯S(thione), methyl-ene-C-H⋯π(pyrid-yl), methyl-ene- and phenyl-C-H⋯π(phen-yl) contacts connect mol-ecules into supra-molecular layers propagating in the bc plane; the layers stack along the a axis with no directional inter-actions between them. The analysis of the Hirshfeld surface indicates the relative importance of an intra-layer phenyl-H⋯H(pyrid-yl) contact upon the mol-ecular packing.

Project description:The title compound, C28H33N2S2P, adopts the thione tautomeric form, as supported by the C-S distance [1.6744?(18)?Å].

In the crystal, pairs of N-N-H hydrogen bonds between the thione groups link neighbouring mol-ecules into centrosymmetric dimers.
