(E)-{[(Butylsulfanyl)methanethioyl]amino}(4-methoxybenzylidene)amine: crystal structure and Hirshfeld surface analysis.

ABSTRACT: The title hydrazine carbodithioate, C13H18N2OS2, is constructed about a central and almost planar C2N2S2 chromophore (r.m.s. deviation = 0.0263?Å); the terminal methoxybenzene group is close to coplanar with this plane [dihedral angle = 3.92?(11)°]. The n-butyl group has an extended all-trans conformation [torsion angles S—Cm—Cm—Cm = ?173.2?(3)° and Cm—Cm—Cm—Cme = 180.0?(4)°; m = methylene and me = methyl]. The most prominent feature of the molecular packing is the formation of centrosymmetric eight-membered {?HNCS}2 synthons, as a result of thioamide-N—H?S(thioamide) hydrogen bonds; these are linked via methoxy-C–H??(methoxybenzene) interactions to form a linear supramolecular chain propagating along the a-axis direction. An analysis of the calculated Hirshfeld surfaces and two-dimensional fingerprint plots point to the significance of H?H (58.4%), S?H/H?S (17.1%), C?H/H?C (8.2%) and O?H/H?O (4.9%) contacts in the packing. The energies of the most significant interactions, i.e. the N—H?S and C—H?? interactions have their most significant contributions from electrostatic and dispersive components, respectively. The energies of two other identified close contacts at close to van der Waals distances, i.e. a thione–sulfur and methoxybenzene–hydrogen contact (occurring within the chains along the a axis) and between methylene-H atoms (occurring between chains to consolidate the three-dimensional architecture), are largely dispersive in nature.

(E)-[({[(3-Methyl-phen-yl)meth-yl]sulfan-yl}methane-thio-yl)amino](1-phenyl-pentyl-idene)amine.

Project description:In the structure of the title compound, C(20)H(24)N(2)S(2), the central CN(2)S(2) atoms are planar (r.m.s. deviation = 0.0205?Å) but both benzene rings are twisted out of this plane forming dihedral angles of 23.03?(6) and 84.75?(4)° (tol-yl); the n-butyl group occupies a position normal to the plane [N-C-C-C torsion angle = -84.33?(16)°]. The conformation of the imine bond [1.2888?(18)?Å] is E. The syn arrangement of the thione S and amino H atoms enables the formation of N-H?S hydrogen bonds between centrosymmetrically related mol-ecules. These lead to eight-membered {?HNC=S}(2) synthons which are further stabilized by proximate C-H?S interactions. The resulting dimeric aggregates are connected into a supra-molecular chain along the c axis by C-H??(tol-yl) inter-actions.

2-[(1E)-({[(Benzyl-sulfan-yl)methane-thio-yl]amino}-imino)-meth-yl]-6-meth-oxy-phenol: crystal structure and Hirshfeld surface analysis.

Project description:The title di-thio-carbazate ester, C16H16N2O2S2, comprises two almost planar residues, i.e. the phenyl ring and the remaining 14 non-H atoms (r.m.s. deviation = 0.0410 Å). These are orientated perpendicularly, forming a dihedral angle of 82.72 (5)°. An intra-molecular hy-droxy-O-H⋯N(imine) hydrogen bond, leading to an S(6) loop, is noted. An analysis of the geometric parameters is consistent with the mol-ecule existing as the thione tautomer, and the conformation about the C=N bond is E. The thione S and imine H atoms lie to the same side of the mol-ecule, facilitating the formation of inter-molecular N-H⋯S hydrogen bonds leading to eight-membered {⋯HNCS}2 synthons in the crystal. These aggregates are connected by phenyl-C-H⋯O(hy-droxy) inter-actions into a supra-molecular layer in the bc plane; these stack with no directional inter-actions between them. An analysis of the Hirshfeld surface confirms the nature of the inter-molecular inter-actions.

4-[(1E)-({[(Benzyl-sulfan-yl)methane-thio-yl]amino}-imino)-meth-yl]benzene-1,3-diol chloro-form hemisolvate: crystal structure, Hirshfeld surface analysis and computational study.

Project description:The title hydrazine carbodi-thio-ate chloro-form hemisolvate, 2C15H14N2O2S2·CHCl3, comprises two independent hydrazine carbodi-thio-ate mol-ecules, A and B, and a chloro-form mol-ecule; the latter is statistically disordered about its mol-ecular threefold axis. The common features of the organic mol-ecules include an almost planar, central CN2S2 chromophore [r.m.s. deviation = 0.0203?Å (A) and 0.0080?Å (B)], an E configuration about the imine bond and an intra-molecular hydroxyl-O-H?N(imine) hydrogen bond. The major conformational difference between the mol-ecules is seen in the relative dispositions of the phenyl rings as indicated by the values of the dihedral angles between the central plane and phenyl ring of 71.21?(6)° (A) and 54.73?(7)° (B). Finally, a difference is seen in the disposition of the outer hydroxyl-H atoms, having opposite relative orientations. In the calculated gas-phase structure, the entire mol-ecule is planar with the exception of the perpendicular phenyl ring. In the mol-ecular packing, the A and B mol-ecules assemble into a two-mol-ecule aggregate via N-H?S hydrogen bonds and eight-membered {?HNCS}2 synthons. The dimeric assemblies are connected into supra-molecular chains via hydroxyl-O-H?O(hydrox-yl) hydrogen bonds and these are linked into a double-chain through hy-droxy-O-H??(phen-yl) inter-actions. The double-chains are connected into a three-dimensional architecture through phenyl-C-H?O(hydrox-yl) and phenyl-C-H??(phen-yl) inter-actions. The overall assembly defines columns along the a-axis direction in which reside the chloro-form mol-ecules, which are stabilized by chloro-form-methine-C-H?S(thione) and phenyl-C-H?Cl contacts. The analysis of the calculated Hirshfeld surfaces, non-covalent inter-action plots and inter-action energies confirm the importance of the above-mentioned inter-actions, but also of cooperative, non-standard inter-actions such as ?(benzene)??(hydrogen-bond-mediated-ring) contacts.

Project description:The title compound, C(10)H(13)N(3)S(2), is roughly planar (r.m.s. deviation = 0.086?Å). In the crystal, N-H?S hydrogen bonds link the mol-ecules into (001) sheets.

N'-[Bis(benzyl-sulfan-yl)methyl-idene]-4-meth-oxy-benzohydrazide.

Project description:In the title compound, C(23)H(22)N(2)O(2)S(2), the dihedral angles between the 4-meth-oxy-substituted phenyl ring and the other two phenyl rings are 84.4?(4) and 77.7?(1)°, respectively, while the dihedral angle between the two phenyl rings is 57.5?(2)°. The amino group is not involved in an N-H hydrogen bond. The crystal packing is established by inter-molecular C-H?O packing inter-actions involving a relatively rare weak three-center hydrogen bond between the keto O atom and H atoms of the two nearby phenyl rings, which link the mol-ecules into chains running along the a axis. Additional weak inter-molecular hydrogen-bond inter-actions between the 4-meth-oxy O atom and one of the phenyl rings and provide added stability to the crystal packing.

Crystal structure of 2-((1E)-{2-[bis-(2-methyl-benzyl-sulfan-yl)methyl-idene]hydrazin-1-yl-idene}meth-yl)-6-meth-oxy-phenol.

Project description:In the title compound, C25H26N2O2S2, the central CN2S2 atoms are almost coplanar (r.m.s. deviation = 0.0058 Å). One phenyl ring clearly lies to one side of the central plane, while the other is oriented in the plane but splayed. Despite the different relative orientations, the phenyl rings form similar dihedral angles of 64.90 (3) and 70.06 (3)° with the central plane, and 63.28 (4)° with each other. The benzene ring is twisted with respect to the central plane, forming a dihedral angle of 13.17 (7)°. The S2C=N, N-N and N-N=C bond lengths of 1.2919 (19), 1.4037 (17) and 1.2892 (19) Å, respectively, suggest limited conjugation over these atoms; the configuration about the N-N=C bond is E. An intra-molecular O-H⋯N hydrogen bond is noted. In the crystal, phen-yl-meth-oxy C-H⋯O and phen-yl-phenyl C-H⋯π inter-actions lead to supra-molecular double chains parallel to the b axis. These are connected into a layer via meth-yl-phenyl C-H⋯π inter-actions, and layers stack along the a axis, being connected by weak π-π inter-actions between phenyl rings [inter-centroid distance = 3.9915 (9) Å] so that a three-dimensional architecture ensues.
