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

ABSTRACT: 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.

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. ...[more]

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

Project description:The asymmetric unit of the title compound, C(13)H(10)N(2)O(4), contains two crystallographically independent mol-ecules. The aromatic rings are oriented at dihedral angles of 24.39?(3) and 7.47?(3)° in the two mol-ecules and intra-molecular N-H?O and O-H?O hydrogen bonds result in the formation of two planar six-membered rings. In the crystal structure, inter-molecular O-H?O and C-H?O hydrogen bonds link the mol-ecules into chains, forming R(2) (2)(10) ring motifs. Weak ?-? contacts between the benzene and phenyl rings [centroid-centroid distance = 3.955?(3)?Å] may further stabilize the structure.

2-Hydr-oxy-5-nitro-benzamide.

Project description:In the title compound, C(7)H(6)N(2)O(4), an intra-molecular O-H?O hydrogen bond generates an S(6) ring. In the crystal, inversion dimers linked by pairs of N-H?O hydrogen bonds occur. Weak C-H?O links consolidate the packing, leading to R(2) (1)(7) and R(2) (2)(10) loops within (100) polymeric sheets.

4-Hydr-oxy-3-nitro-benzaldehyde.

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.

3-Hydr-oxy-N'-(5-hydr-oxy-2-nitro-benzyl-idene)-2-naphthohydrazide.

Project description:The mol-ecule of the title compound, C(18)H(13)N(3)O(5), displays an E configuration with respect to the C=N double bond. The dihedral angle between the benzene ring and the naphthyl system is 1.1?(2)°. In the crystal structure, mol-ecules are linked through inter-molecular N-H?O and O-H?O hydrogen bonds, forming 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.

N-(4-Hydr-oxy-3-methoxy-benz-yl)benzamide.

Project description:In the mol-ecular structure of the title compound, C(15)H(15)NO(3), the two benzene rings are twisted with respect to each other, making a dihedral angle of 75.11?(10)°. In the amide fragment, the C=O and C-N bond distances are 1.248?(3) and 1.321?(3)?Å, respectively, indicating electron delocalization. A partially ovelapped arrangement between parallel hydroxy-methoxy-benzene rings is observed in the crystal structure, and the face-to-face distance of 3.531?(16)?Å suggests the existence of weak ?-? stacking. N-H?O and O-H?O hydrogen bonding is also present in the crystal structure.

5-Hydr-oxy-8-nitro-1,4-naphthoquinone.

Project description:The title compound, C(10)H(5)NO(5), features an intra-molecular O-H?O hydrogen bond, forming a six-membered ring with an S(6) ring motif. The nitro group makes a dihedral angle of 71.66?(5)° with the plane of the benzene ring to which it is bound. The two rings are almost coplanar, with a dihedral angle of 4.44?(5)°. Short inter-molecular distances between the centroids of the six-membered rings [3.7188?(6)-3.8299?(6)?Å] indicate the existence of ?-? inter-actions. The inter-esting features of the crystal structure are the short inter-molecular O?O and O?N inter-actions. The crystal packing is stabilized by intra-molecular O-H?O and inter-molecular C-H?O (×3) hydrogen bonds, and C-H?? inter-actions.
