4-{[(E)-2,3-Dihy-droxy-benzyl-idene]amino}-N-(5-methyl-1,2-oxazol-3-yl)benzene-sulfonamide.

ABSTRACT: In the title compound, C(17)H(15)N(3)O(5)S, the 2,3-dihy-droxy-benzaldehyde unit is oriented at a dihedral angles of 16.83 (10) and 78.87 (6)° with the anilinic and 5-methyl-1,2-oxazol-3-amine groups, respectively. An S(6) loop exists due to intramolecular O-H⋯N hydrogen bonding. In the crystal, inversion dimers with R(2) (2)(8) rings are formed due to N-H⋯N hydrogen bonding between the 5-methyl-1,2-oxazol-3-amine groups. These dimers are inter-linked by O-H⋯O hydrogen bonds, forming chains along [101] and resulting in R(2) (2)(26) rings. π-π inter-actions occur between the central benzene rings with a centroid-centroid distance of 3.7928 (16) Å.

N'-(2,3-Dihy-droxy-benzyl-idene)isonicotinohydrazide.

Project description:The title compound, C(13)H(11)N(3)O(3), crystallized with two independent mol-ecules in the asymmetric unit. One of the mol-ecules is twisted while the other is almost planar, with dihedral angles of 28.02 (6) and 2.42 (9)°, respectively, between the benzene and pyridine rings. Intra-molecular O-H⋯O and O-H⋯N hydrogen bonds are present in both mol-ecules. The two independent mol-ecules are linked by pairs of O-H⋯O hydrogen bonds. The crystal structure is further stabilized by inter-molecular N-H⋯N hydrogen bonds and C-H⋯N and C-H⋯O inter-actions.

N'-[(E)-2,3-Dihy-droxy-benzyl-idene]-2-meth-oxy-benzohydrazide.

Project description:The title compound, C15H14N2O4 adopts an E conformation about the azomethine double bond. Intra-molecular N-H?O and O-H?N hydrogen bonds generate S(6) rings and help to establish the molecular conformation. The dihedral angle between the benzene rings is 17.84?(10)°. In the crystal, mol-ecules are linked by O-H?O and C-H?O hydrogen bonds into a two-dimensional network with a herring-bone pattern arranged parallel to the bc plane.

(E)-N'-(2,3-Dihy-droxy-benzyl-idene)-4-meth-oxy-benzohydrazide.

Project description:The mol-ecule of the title benzohydrazide derivative, C(15)H(14)N(2)O(4), is twisted and exists in a trans conformation with respect to the C=N double bond. The dihedral angle between the benzene rings is 56.86 (9)° and the C atom of the meth-oxy group deviates slightly [C-O-C-C = -10.4 (3)°] from its attached benzene ring. An intra-molecular O-H⋯N hydrogen bond generates an S(6) ring. In the crystal, mol-ecules are linked by N-H⋯O and bifurcated N-H⋯(O,O) hydrogen bonds, as well as weak C-H⋯O inter-actions, into two-dimensional networks lying parallel to the bc plane. A weak C-H⋯π inter-action also occurs.

4-[(2-Hy-droxy-5-nitro-benzyl-idene)amino]-benzene-sulfonamide.

Project description:The title Schiff base compound, C(13)H(11)N(3)O(5)S, exists in an E configuration with respect to the C=N double bond. The benzene rings are almost coplanar, making a dihedral angle of 2.82 (6). The sulfonamide group is twisted away from the attached phenyl ring with an N-S-C-C torsion angle of 64.84 (11)°. An intra-molecular O-H⋯N hydrogen bond stabilizes the mol-ecule, generating an S(6) ring motif. In the crystal, inter-molecular N-H⋯O and C-H⋯O hydrogen bonds link the mol-ecules into a three-dimensional network.

4-{[4-(Di-methyl-amino)-benzyl-idene]amino}-benzene-sulfonamide.

Project description:The title Schiff base compound, C15H17N3O2S, is non-planar with a dihedral angle of 69.88 (4)° between the planes of the benzene rings. In the crystal, pairs of N-H⋯N hydrogen bonds, between the sulfonamide nitro-gen-H atom and the azomethine N atom, link the mol-ecules into inversion dimers, forming R 2 (2)(16) ring motifs. These dimers are linked by N-H⋯O hydrogen bonds, between the sulfonamide nitro-gen-H atom and one sulfonamide O atom, forming sheets lying parallel to (100). Within the sheets there are weak parallel slipped π-π inter-actions involving inversion-related benzene-sulfonamide rings [centroid-centroid distance = 3.8800 (9) Å; normal distance = 3.4796 (6) Å; slippage = 1.717 Å].

Crystal structure of 3,6-dihy-droxy-4,5-di-methyl-benzene-1,2-dicarbaldehyde.

Project description:The title compound, C10H10O4, was synthesized from tetra-methyl-1,4-benzo-quinone. In the crystal, the almost planar mol-ecule (r.m.s. deviation = 0.024 Å) forms intra-molecular hydrogen bonds between the aldehyde and hy-droxy groups and exhibits C 2v symmetry. This achiral mol-ecule crystallizes in the chiral space group P21 with inter-molecular O-H⋯O and C-H⋯O hydrogen bonding and C-H⋯π and C=O⋯π inter-actions stabilizing the crystal packing.

Benzyl N-(1-{N'-[(E)-2,3-dihy-droxy-benzyl-idene]hydrazinecarbon-yl}-2-hy-droxy-eth-yl)carbamate dihydrate.

Project description:The organic mol-ecule in the title dihydrate, C(18)H(19)N(3)O(6)·2H(2)O, adopts a twisted U-shape with the major twists evident about the chiral C atom [the C-N-C-C torsion angle is -88.2 (4) °] and about the oxygen-benzyl bond [C-O-C-C = 74.2 (4) °]. The conformation about the imine bond [1.290 (4) Å] is E and an intra-molecular O-H⋯N hydrogen bond helps to establish the near coplanarity of the hy-droxy-benzene and hydrazine groups. The crystal packing features O-H⋯O and N-H⋯O hydrogen bonds, leading to two-dimensional supra-molecular arrays in the ab plane with weak C-H⋯π connections between the arrays.

There is also an intra-molecular C-H⋯O hydrogen bond completing an S(6) ring motif. The polymeric chains are inter-linked through inter-molecular C-H⋯O hydrogen bonds.

4-[(2-Hy-droxy-benzyl-idene)amino]-N-(5-methyl-isoxazol-3-yl)benzene-sulfonamide: a monoclinic polymorph.

Project description:The title compound, C(17)H(15)N(3)O(4)S, is a monoclinic polymorph with space group P2(1)/c of the previously reported triclinic form in P [Subashini et al. (2009 ▶). J. Chem. Crystallogr.39, 112-116]. In both polymorphs, intra-molecular O-H⋯N hydrogen bonds and dimer formation via a pair of inter-molecular N-H⋯N hydrogen bonds with an R(2) (2)(8) motif are observed. The two polymorphs differ in the next level of supra-molecular organization involving C-H⋯O hydrogen bonds with varied packing and different conformations.
