Crystal structure of S-hexyl (E)-3-(4-methyl-benzyl-idene)di-thio-carbazate.

ABSTRACT: In the title compound, C15H22N2S2, the di-thio-carbazate group adopts an E conformation with respect to the C=N bond of the benzyl-idene moiety. In the crystal, mol-ecules are linked by pairs of N-H?S hydrogen bonds, forming inversion dimers with an R (2) 2(8) ring motif. The dimers are linked via C-H?? inter-actions, forming chains propagating along [100].

Crystal structure of S-hexyl (E)-3-(2-hy-droxy-benzyl-idene)di-thio-carbazate.

Project description:The title compound, C14H20N2OS2 [systematic name: S-hexyl (E)-2-(2-hy-droxy-benzyl-idene)hydrazine-1-carbodi-thio-ate], crystallizes with four independent mol-ecules (A-D) in the asymmetric unit. All four mol-ecules adopt an E conformation with respect to the C=N bond of the benzyl-idene moiety and have an intra-molecular O-H⋯N hydrogen bond generating an S(6) ring motif. In the crystal, the A and D mol-ecules are connected by a pair N-H⋯S hydrogen bonds, forming a dimer with an R 2 (2)(8) ring motif. In the case of mol-ecules B and C, they are linked to themselves by pairs of N-H⋯S hydrogen bonds, forming B-B and C-C inversion dimers with R 2 (2)(8) ring motifs.

Crystal structure of benzyl 3-(3-methyl-phen-yl)di-thio-carbazate.

Project description:In the title compound, C15H16N2S2, the central CN2S2 residue is almost planar (r.m.s. deviation = 0.0354 Å) and forms dihedral angles of 56.02 (4) and 75.52 (4)° with the phenyl and tolyl rings, respectively; the dihedral angle between the aromatic rings is 81.72 (5)°. The conformation about the N-N bond is gauche [C-N-N-C = -117.48 (15)°]. Overall, the mol-ecule has the shape of the letter L. In the crystal packing, supra-molecular chains along the a axis are formed by N-H⋯S(thione) hydrogen bonds whereby the thione S atom accepts two such bonds. The hydrogen bonding leads to alternating edge-shared eight-membered {⋯HNCS}2 and 10-membered {⋯HNNH⋯S}2 synthons. The chains are connected into layers by phen-yl-tolyl C-H⋯π inter-actions; the layers stack along the c axis with no specific inter-actions between them.

Project description: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.

The dimers are linked by weak π-π inter-actions, with centroid-to-centroid distances of 3.723 (11) Å, forming chains parallel to [110].

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.

Crystal structure of 3-benzyl-1-[(cyclo-hexyl-idene)amino]-thio-urea.

Project description:The conformation of the title compound, C14H19N3S, is partially determined by an intra-molecular N-H⋯N hydro-gen-bond inter-action, although the N-H⋯N angle of 108° is quite small.

In the crystal, mol-ecules are linked by pairs of N-H⋯S hydrogen bonds, forming inversion dimers, with an R 2 (2)(8) ring motif. The dimers are reinforced by pairs of C-H⋯S hydrogen bonds, and are linked by further weak C-H⋯S hydrogen bonds, forming chains propagating along [100].
