2-Hydr-oxy-5-nitro-benzaldehyde.

ABSTRACT: The title compound, C(7)H(5)NO(4), is essentially planar, with a maximum deviation from the mean plane of 0.0116?(11)?Å for the hydr-oxy O atom. The mol-ecular and crystal structure are stabilized by intra- and inter-molecular inter-actions. An intra-molecular O-H?O hydrogen bond generates a six-membered ring, producing an S(6) ring motif. The C-H?O inter-actions result in the formation of C(5) chains and R(2) (2)(8) rings forming an approximately planar network parallel to (10). These planes are inter-connected through ?-? inter-actions [centroid-centroid distance 3.582?(2)?Å].

The title compound, C(7)H(5)NO(4), is essentially planar, with a maximum deviation from the mean plane of 0.0116 (11) Å for the hydr-oxy O atom. The mol-ecular and crystal structure are stabilized by intra- and inter-molecular inter-actions. An intra-molecular O-H⋯O hydrogen bond generates a six-membered ring, producing an S(6) ring motif. The C-H⋯O inter-actions result in the formation of C(5) chains and R(2) (2)(8) rings forming an approximately planar network parallel to (10). These planes ar ...[more]

Project description:The hydroxyl group in each of the two independent mol-ecules of the title compound, C(7)H(5)NO(4), participates in two O-H⋯O hydrogen bonds, viz. one intra-molecular bond to the nitro group and one inter-molecular bond to the aldehyde group of the same mol-ecule in the next unit, resulting in a linear chain structure. The dihedral angle between the aromatic ring and the nitro group is 10.9 (3)° in one mol-ecule and 9.9 (2)° in the other.

2-Hydr-oxy-5-nitro-benzaldehyde 2,4-dinitro-phenyl-hydrazone.

Project description:In the title compound, C(13)H(9)N(5)O(7), one of the nitro groups is twisted away from the attached benzene ring by 16.21 (8)°. The dihedral angle between the two benzene rings is 4.63 (1)°. The mol-ecular structure is stabilized by intra-molecular N-H⋯O and O-H⋯N hydrogen bonds which generate an S(6) ring motif. The mol-ecules pack as layers parallel to the ab plane; mol-ecules of adjacent layers are linked into chains along the [101] direction through N-H⋯O hydrogen bonds.

2-Hydr-oxy-3-nitro-benzamide.

Project description:The asymmetric unit of title compound, C(7)H(6)N(2)O(4), contains two mol-ecules, one of which has a disordered nitro group with an occupancy ratio of 0.517?(9):0.483?(9) for the O atoms. Both mol-ecules contain an intra-molecular O-H?O hydrogen bond. In the crystal, both mol-ecules form inversion dimers linked by pairs of N-H?O hydrogen bonds, resulting in R(2) (2)(8) ring motifs. The dimers are connected by further N-H?O links and weak C-H?O inter-actions, resulting in a layered motif.

(E)-2-Hydr-oxy-3-methoxy-benzaldehyde thio-semicarbazone.

Project description:In the title compound, C(9)H(11)N(3)O(2)S, intra-molecular O-H?O and N-H?N hydrogen bonds contribute to the planarity of the mol-ecular skeleton. Inter-molecular N-H?O hydrogen bonds link the mol-ecules into zigzag chains along the b axis; these mol-ecules are futher paired by ?-? inter-actions [centroid-centroid distance 4.495?(5)?Å]. The crystal structure also exhibits weak inter-molecular N-H?S and O-H?S hydrogen bonds.

3-Hydr-oxy-4-methoxy-benzaldehyde thio-semicarbazone hemihydrate.

Project description:The asymmetric unit of the title compound, C(9)H(11)N(3)O(2)S·0.5H(2)O, comprises two crystallograpically independent thio-semicarbazone mol-ecules (A and B) and a water mol-ecule of crystallization. In each of the thio-semicarbazone mol-ecules, intra-molecular O-H⋯O and N-H⋯N hydrogen bonds form five-membered rings, producing S(5) ring motifs. Inter-molecular O-H⋯S and N-H⋯O inter-actions between mol-ecule B and the water mol-ecule form a six-membered ring, producing an R(2) (2)(6) ring motif. Inter-molecular N-H⋯S hydrogen bonds form dimers involving pairs of both A and B mol-ecules, which form R(2) (2)(8) ring motifs. The angles between the aromatic ring and thio-urea unit in the two mol-ecules are 0.80 (6) and 3.28 (5)°, which proves that each mol-ecule is fairly planar. The crystal structure is stabilized by inter-molecular O-H⋯S (×2), O-H⋯O, N-H⋯S (×2) and N-H⋯O (×2) hydrogen bonds and C-H⋯O (×2) contacts to form a three-dimensional network.

4-Hydr-oxy-3-meth-oxy-5-nitro-aceto-phenone (5-nitro-apocynin).

Project description:The title mol-ecule, C(9)H(9)NO(5), is close to planar (r.m.s. deviation from the mean plane of the non-H atoms = 0.058 Å). The OH group forms a bifurcated O-H⋯(O,O) hydrogen bond, with the intra-molecular component to a nitro O atom and the inter-molecular component to a keto O atom, the latter resulting in chains along [20]. A C-H⋯O inter-action reinforces the packing.
