5-Chloro-8-hydr-oxy-6-methyl-1,4-naphthoquinone.

ABSTRACT: The mol-ecule of the title compound, C(11)H(7)ClO(3), is planar, with a maximum deviation of 0.0383?(10)?Å from the naphthoquinone plane. An intra-molecular O-H?O hydrogen bond generates an S(6) ring motif. The crystal packing is stabilized by inter-molecular C-H?O hydrogen bonds. Short intra-molecular Cl?O [2.8234?(8)?Å] and O?O [2.5530?(11)?Å], and inter-molecular Cl?Cl [3.2777?(3)?Å] contacts further stabilize the crystal structure.

The mol-ecule of the title compound, C(11)H(7)ClO(3), is planar, with a maximum deviation of 0.0383 (10) Å from the naphthoquinone plane. An intra-molecular O-H⋯O hydrogen bond generates an S(6) ring motif. The crystal packing is stabilized by inter-molecular C-H⋯O hydrogen bonds. Short intra-molecular Cl⋯O [2.8234 (8) Å] and O⋯O [2.5530 (11) Å], and inter-molecular Cl⋯Cl [3.2777 (3) Å] contacts further stabilize the crystal structure. ...[more]

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.

2-Chloro-3-(4-chloro-benzamido)-1,4-naphthoquinone.

Project description:The naphthoquinone ring is almost perpendicular [dihedral angle 71.02?(3)°] to the phenyl group of the title compound, C(17)H(9)Cl(2)NO(3), while the dihedral angle between the amide group and the 4-chloro-phenyl ring is 21.9?(2)°. The conformation of the N-H and C=O bonds are anti to each other. N-H?Cl hydrogen bonds link the mol-ecules into chains in the a-axis direction. In addition, these chains are linked by weak inter-molecular C-H?O inter-actions.

6-Chloro-N'-(2-hydr-oxy-1-naphthyl-methyl-ene)nicotinohydrazide.

Project description:The title compound, C(17)H(12)ClN(3)O(2), was synthesized by the Schiff base condensation reaction of 2-hydr-oxy-1-naphthaldehyde with 6-chloro-nicotinic acid hydrazide in a methanol solution. The mol-ecule displays a trans configuration with respect to the C=N and C-N bonds. The dihedral angle between the naphthyl ring system and the pyridine ring is 7.6?(4)°. There is an intra-molecular O-H?N hydrogen bond. The crystal structure is stabilized by inter-molecular N-H?O and C-H?O hydrogen bonds, forming chains running along the b axis.

N'-(2-Chloro-benzyl-idene)-2-hydr-oxy-3-methyl-benzohydrazide.

Project description:In the title compound, C(15)H(13)ClN(2)O(2), the dihedral angle between the two benzene rings is 3.4?(5)° and the mol-ecule adopts an E configuration with respect to the C=N bond. There is an intra-molecular O-H?O hydrogen bond in the mol-ecule, which generates an S(6) loop. In the crystal structure, mol-ecules are linked through inter-molecular N-H?O hydrogen bonds, forming C(4) chains running along the a axis.

Project description:In the title compound, C(15)H(14)O(5), an intramolecular O-H?O hydrogen bond occurs. In the crystal, the molecules form inversion dimers linked by pairs of O-H?O bonds, which are further linked by C-H?O interactions.

4-Chloro-7-hydr-oxy-6-methyl-1,7-naphthyridin-8(7H)-one.

Project description:The title compound, C(9)H(7)ClN(2)O(2), was prepared by reaction of methyl 4-chloro-3-(prop-1-yn-yl)picolinate with hydroxy-l-amine in MeOH/KOH solution. The two essentially planar mol-ecules which make up the asymmetric unit have almost identical geometries and and are linked into dimeric aggregates via pairs of O-H?O hydrogen bonds. These aggregates have almost perfect inversion symmetry; however, quite unusually, the inversion center of the dimer does not coincide with the crystallographic inversion center.

(E)-2-Chloro-N'-(2-hydr-oxy-1-naphthyl-methyl-ene)benzohydrazide.

Project description:In the structue of the title compound, C(18)H(13)ClN(2)O(2), a new Schiff base, the dihedral angle between the benzene and naphthyl ring system mean planes is 22.5?(2)°. The mol-ecule has an E configuration about the C=N bond, and an intra-molecular hydrogen bond involving the hydoxyl substituent on the naphthyl ring and the N' atom of the hydrazide. The crystal structure is stabilized by inter-molecular N-H?O hydrogen bonds, forming one-dimensional chains running parallel to the a axis.

The cocrystal 2-hydr-oxy-4-methyl-N-propanoylbenzohydrazide-2-hydr-oxy-N-(2-hydr-oxy-4-methyl-benzo-yl)-6-methyl-benzohydrazide (2/1).

Project description:The asymmetric unit of the title compound, 2C(11)H(14)N(2)O(3)·C(16)H(16)N(2)O(4), contains one mol-ecule of 2-hydr-oxy-4-methyl-N-propanoylbenzohydrazide and one-half of a mol-ecule of 2-hydr-oxy-N-(2-hydr-oxy-4-methyl-benzo-yl)-6-methyl-benzohydrazide. The latter is located on a centre of inversion. Intra-molecular N-H?O inter-actions stabilize the conformations of both mol-ecules. The crystal structure is stabilized by inter-molecular N-H?O and O-H?O hydrogen bonds.

Methyl 5-chloro-2-hydr-oxy-3-(4-methoxy-phen-yl)-4,6-dimethyl-benzoate.

Project description:In the title compound, C(17)H(17)ClO(4), the dihedral angle between the mean planes of the two benzene rings is 65.92 (5)°. The methyl ester group lies within the ring plane [deviations of O atoms from the plane = -0.051 (2) and 0.151 (2) Å] due to an intra-molecular O-H⋯O hydrogen bond. In the crystal, mol-ecules are held together by rather weak non-classical inter-molecular C-H⋯O hydrogen bonds, resulting in dimeric units about inversion centers, forming eight- and ten-membered ring systems as R(2) (2)(8) and R(2) (2)(10) motifs.

Project description:In the title mol-ecule, C(18)H(14)N(2)O(3), O-H?N and N-H?O hydrogen bonds influence the mol-ecular conformation; the benzene and naphthalene planes are inclined at a dihedral angle of 11.54?(5)°. In the crystal structure, inter-molecular O-H?O hydrogen bonds link the mol-ecules into chains running in the [01] direction.
