3-[(3,4-Dichloro-phen-yl)amino-carbon-yl]propionic acid.

ABSTRACT: In the title compound, C(10)H(9)Cl(2)NO(3), inversion dimers occur due to pairs of inter-molecular O-H?O hydrogen bonds from the carboxyl groups forming R(2) (2)(8) loops. The dimers are linked into C(4) chains along the a axis by inter-molecular N-H?O links. A short intra-molecular C-H?O contact occurs in the mol-ecule.

In the title compound, C(10)H(9)Cl(2)NO(3), inversion dimers occur due to pairs of inter-molecular O-H⋯O hydrogen bonds from the carboxyl groups forming R(2) (2)(8) loops. The dimers are linked into C(4) chains along the a axis by inter-molecular N-H⋯O links. A short intra-molecular C-H⋯O contact occurs in the mol-ecule. ...[more]

Project description:In the crystal structure of the title compound, C(10)H(9)Cl(2)NO(3)·H(2)O, the conformations of the amide O atom and the carbonyl O atom of the acid segment are anti to the H atoms of adjacent -CH(2) groups. In the crystal, the mol-ecules are linked into a three-dimensional network through N-H?O and O-H?O inter-molecular hydrogen bonds.

3-[(3,5-Dichloro-anilino)carbon-yl]propionic acid.

Project description:In the crystal structure of the title compound, C(10)H(9)Cl(2)NO(3), the conformations of the amide O atom and the carbonyl O atom of the acid segment are anti to the H atoms of the adjacent -CH(2) groups. The C=O and O-H bonds of the acid group are in relatively rare anti positions with respect to each other. This is an obvious consequence of the concerted effects of both the all-anti mol-ecular conformation and the intermolecular hydrogen bond donated to the amide carbonyl group. In the crystal, mol-ecules are packed into infinite chains through inter-molecular N-H?O and O-H?O hydrogen bonds.

2,4-Dichloro-N-(3,4-dichloro-phen-yl)benzene-sulfonamide.

Project description:In the crystal structure of the title compound, C(12)H(7)Cl(4)NO(2)S, the conformation of the N-H bond is syn to the meta-chloro residue in the aniline benzene ring. The two aromatic rings are tilted relative to each other by 68.9?(1)°. N-H?O hydrogen bonds connect the mol-ecules into centrosymmetric dimers.

3-(3,5-Dichloro-anilinocarbon-yl)propionic acid.

Project description:The crystal structure of the title compound, C(10)H(9)Cl(2)NO(3), consists of dimers due to inter-molecular O-H?O hydrogen bonding forming an R(2) (2)(8) ring through the carboxyl- groups. These dimers are linked to each other by inter-molecular hydrogen bonds between the amine group and the adjacent carbonyl O atom. A single C-Cl?? inter-action is also observed between the chloro-substituted aromatic rings.

Bis[4-(dimethyl-amino)pyridinium] tetra-bromidobis(3,4-dichloro-phen-yl)stannate(IV)-1-bromo-3,4-dichloro-benzene (1/1).

Project description:The Sn atom in the title substituted pyridinium stannate bromo-3,4-dichloro-benzene solvate, (C(7)H(11)N(2))(2)[SnBr(4)(C(6)H(3)Cl(2))(2)]·C(6)H(3)BrCl(2), lies on a twofold axis within an octa-hedral C(2)Br(4) donor set. Each cation forms an N-H?Br hydrogen bond to one of the Br atoms of the anion. The solvent mol-ecule is disordered about the twofold rotation axis with equal occupancy. The crystal under investigation was non-merohedrally twinned, with a twin component ratio of 0.76:0.24.

N-(3,4-Dichloro-phen-yl)maleamic acid.

Project description:The asymmetric unit of the title compound, C(10)H(7)Cl(2)NO(3), contains two unique mol-ecules, both being stabilized by an intra-molecular O-H?O hydrogen bond within their maleamic units. In the crystal structure, inter-molecular N-H?O hydrogen bonds link the mol-ecules into chains extending along [1] which are further assembled into sheets via short inter-molecular C-Cl?O=C contacts [3.102?(2) and 3.044?(2)?Å].

N-(3,4-Dichloro-phen-yl)-3-oxo-butanamide.

Project description:In the title compound. C(10)H(9)Cl(2)NO(2), the acetamide residue is twisted out of the phenyl ring plane by 25.40?(9)°. An intra-molecular C-H?O close contact is observed. The N atom of the butanamide unit forms an inter-molecular N-H?O hydrogen bond with the symmetry-related carbonyl O atom, inter-linking mol-ecules into a C(4) chain along [100]. Additional C-H?O inter-molecular inter-actions and Cl?Cl contacts [3.4364?(8)?Å] contribute to the stability of the crystal packing.

2,2-Dichloro-N-(3,4-dimethyl-phen-yl)acetamide.

Project description:In the title compound, C(10)H(11)Cl(2)NO, the N-H bond is syn to the 3-methyl substituent in the aromatic ring, similar to that observed in N-(3,4-dimethyl-phen-yl)acetamide and to the 3-chloro substituent in 2,2-dichloro-N-(3,4-dichloro-phen-yl)acetamide, and contrasting with the anti conformation observed for the 3-methyl substituent in 2,2,2-trichloro-N-(3,4-dimethyl-phen-yl)acetamide. On the other hand, it is anti to the C=O bond. An inter-molecular N-H?O hydrogen bond links mol-ecules into infinite chains along the b axis.
