Crystal structure and Hirshfeld surface analysis of 2-{[(E)-(3-cyclo-butyl-1H-1,2,4-triazol-5-yl)imino]-meth-yl}phenol.

ABSTRACT: The title compound, C₁₃H₁₄N₄O, was developed using the reaction of salicyl-aldehyde and 3-amino-5-cyclo-butyl-1,2,4-triazole in ethanol under microwave irradiation. This eco-friendly microwave-promoted method proved to be efficient in the synthesis of 2-{[(E)-(3-cyclo-butyl-1H-1,2,4-triazol-5-yl)imino]-meth-yl}phenol in good yields and purity. The title compound is a Schiff base that exists in the phenol-imine tautomeric form and adopts an E configuration. The three independent mol-ecules in the asymmetric unit (A, B and C) are not planar, the cyclo-butyl and the phenol-imine rings are twisted to each other making a dihedral angle of 67.8 (4)° in mol-ecule A, 69.1 (2)° in mol-ecule B and 89.1 (2)° in mol-ecule C. In each mol-ecule an intra-molecular O-H⋯N hydrogen bond is present, forming an S(6) ring motif. A Hirshfeld surface analysis was performed to investigate the contributions of the different inter-molecular contacts within the supra-molecular structure. The major inter-actions are H⋯H (53%), C⋯H (19%) and N⋯H (17%) for mol-ecule A, H⋯H (50%), N⋯H (20%) and C⋯H (20%) for mol-ecule B and H⋯H (57%), C⋯H (14%) and N⋯H (13%) for mol-ecule C.

Crystal structure of 4-{[(1H-1,2,4-triazol-1-yl)meth-yl]sulfan-yl}phenol.

Project description:In the title compound, C9H9N3OS, the plane of the benzene ring forms a dihedral angle of 33.40?(5)° with that of the triazole group. In the crystal, mol-ecules are linked by O-H?N hydrogen bonds involving the phenol -OH group and one of the unsubstituted N atoms of the triazole ring, resulting in chains along [010]. These chains are further extended into a layer parallel to (001) by weak C-H?N hydrogen-bond inter-actions. Aromatic ?-? stacking [centroid-centroid separation = 3.556?(1)?Å] between the triazole rings links the layers into a three-dimensional network.

2-tert-Butyl-6-(cyclo-hexyl-imino-meth-yl)-4-meth-oxy-phenol.

Project description:The asymmetric unit of the title Schiff base compound, C(18)H(27)NO(2), contains two independent mol-ecules in which the C=N bond lengths are 1.278?(2) and 1.280?(2)?Å and the cyclo-hexane rings adopt chair conformations. Intra-molecular O-H?N hydrogen bonding between hy-droxy and imine groups and weak C-H?O hydrogen bonds help to stabilize the mol-ecular structure.

Project description:The asymmetric unit of the title Schiff base compound, C(21)H(21)NO, contains two crystallographicaly independent mol-ecules.

An intra-molecular O-H?N hydrogen bond and weak intra-molecular C-H?O hydrogen bonds stabilize the structure of each independent mol-ecule.

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.

Crystal structure, Hirshfeld surface analysis and DFT studies of 4-methyl-2-({[4-(tri-fluoro-meth-yl)phen-yl]imino}-meth-yl)phenol.

Project description:The title compound, C15H12F3NO, crystallizes with one mol-ecule in the asymmetric unit. The configuration of the C=N bond is E and there is an intra-molecular O-H⋯N hydrogen bond present, forming an S(6) ring motif. The dihedral angle between the mean planes of the phenol and the 4-tri-fluoro-methyl-phenyl rings is 44.77 (3)°. In the crystal, mol-ecules are linked by C-H⋯O inter-actions, forming polymeric chains extending along the a-axis direction. The Hirshfeld surface analysis indicates that the most important contributions to the crystal packing are from C⋯H/H⋯C (29.2%), H⋯H (28.6%), F⋯H/H⋯F (25.6%), O⋯H/H⋯O (5.7%) and F⋯F (4.6%) inter-actions. The density functional theory (DFT) optimized structure at the B3LYP/6-311 G(d,p) level is compared with the experimentally determined mol-ecular structure in the solid state. The HOMO-LUMO behaviour was elucidated to determine the energy gap. The crystal studied was refined as an inversion twin.

Crystal structure and DFT computational studies of (E)-2,4-di-tert-butyl-6-{[3-(tri-fluoro-meth-yl)benz-yl]imino-meth-yl}phenol.

Project description:The title compound, C23H28F3NO, is an ortho-hy-droxy Schiff base compound, which adopts the enol-imine tautomeric form in the solid state. The mol-ecular structure is not planar and the dihedral angle between the planes of the aromatic rings is 85.52?(10)°. The tri-fluoro-methyl group shows rotational disorder over two sites, with occupancies of 0.798?(6) and 0.202?(6). An intra-molecular O-H?N hydrogen bonding generates an S(6) ring motif. The crystal structure is consolidated by C-H?? inter-actions. The mol-ecular structure was optimized via density functional theory (DFT) methods with the B3LYP functional and LanL2DZ basis set. The theoretical structure is in good agreement with the experimental data. The frontier orbitals and mol-ecular electrostatic potential map were also examined by DFT computations.
