Dimethyl 4,5-dichlorobenzene-1,2-dicarboxyl-ate.

ABSTRACT: In the title compound, C(10)H(8)Cl(2)O(4), the two Cl atoms and one of the meth-oxy-carbonyl groups are almost coplanar [maxi-mum derivation = 0.035?(2)?Å] with the benzene plane, and the other meth-oxy-carbonyl group exhibits an almost orthogonal disposition relative to the benzene plane, with a dihedral angle of 84.82?(3)° between the planes. In the crystal, the molecules are connected into a chain propagating along the [011] direction through nonclassical C-H?O hydrogen bonds.

In the title compound, C(10)H(8)Cl(2)O(4), the two Cl atoms and one of the meth-oxy-carbonyl groups are almost coplanar [maxi-mum derivation = 0.035 (2) Å] with the benzene plane, and the other meth-oxy-carbonyl group exhibits an almost orthogonal disposition relative to the benzene plane, with a dihedral angle of 84.82 (3)° between the planes. In the crystal, the molecules are connected into a chain propagating along the [011] direction through nonclassical C-H⋯O hydrogen bonds. ...[more]

Project description:In the crystal of the title compound, C(14)H(15)NO(4), pairs of inter-molecular N-H⋯O hydrogen bonds link the mol-ecules into centrosymmetric R(2) (2)(10) dimers. These dimers are further connected via inter-molecular C-H⋯O hydrogen bonds, forming a three-dimensional network. The heterocyclic ring adopts a twisted conformation.

Bis(benzyl-aminium) 4,5-dichloro-benzene-1,2-dicarboxyl-ate monohydrate.

Project description:In the structure of the title salt, 2C(7)H(10)N(+)·C(8)H(2)Cl(2)O(4) (2-)·H(2)O, the two benzyl-aminium anions have different conformations, one being essentially planar and the other having the side chain rotated out of the benzene plane [minimum ring to side-chain C-C-C-N torsion angles = -3.6?(6) and 50.1?(5)°, respectively]. In the 4,5-dichloro-phthalate dianion, the carboxyl-ate groups make dihedral angles of 23.0?(2) and 76.5?(2)° with the benzene ring. In the crystal, aminium N-H?O and water O-H?O hydrogen-bonding associations with carboxyl-ate O-atom acceptors give a two-dimensional duplex sheet structure which extends along the (011) plane. Weak ?-? inter-actions are also present between the benzene ring of the dianion and one of the cation rings [minimum ring centroid separation = 2.749?(3)?Å].

Dimethyl 9-benzyl-3-cyano-9H-pyrrolo[1,2-a]benzimidazole-1,2-dicarboxyl-ate.

Project description:The title compound, C(22)H(17)N(3)O(4), was prepared through 1,3-dipolar cyclo-addition: the dihedral angle between the benzimidazole and benzene rings is 80.93?(6)°. The crystal structure is stabilized by weak ?-? inter-actions between the planar pyrrolobenzimidazole rings (r.m.s. deviation = 0.0293?Å) of neighbouring mol-ecules, forming chains along the c axis. The perpendicular distance is 3.47?(2)?Å and the centroid-centroid distances are in the range of 3.590?(3)-3.944?(3)?Å.

Dimethyl 8-acetyl-2-methyl-1,2-dihydro-quinoline-2,4-dicarboxyl-ate.

Project description:In the title compound, C(16)H(17)NO(5), the six-membered N-containing ring has a half-boat form; the spiro C atom deviates by 0.34 (2) Å from the plane (r.m.s. deviation = 0.051 Å) defined by the N and four aromatic C atoms. Intra-molecular N-H⋯O hydrogen bonding generates an S(6) ring motif and the dihedral angle between the mean plane though the S(6) ring and that through the five-atom half-boat plane is 3.39 (2)°. In the crystal, weak inter-molecular C-H⋯O hydrogen bonds link mol-ecules into zigzag chains along [001] due to c-glide symmetry, and C-H⋯π inter-actions extend along [010].
