Dimethyl 3,3'-diphenyl-2,2'-[(S)-thio-phene-2,5-diylbis(carbonyl-aza-nedi-yl)]dipropano-ate.

ABSTRACT: The asymmetric unit of the title compound, C(26)H(26)N(2)O(6)S, contains two independent mol-ecules; each has twofold symmetry with the S atom and the mid-point of the C-C bond of the thio-phene ring located on a twofold rotation axis. In the two mol-ecules, the terminal benzene rings are oriented at dihedral angles of 65.8?(3) and 63.5?(3)° with respect to the central thio-phene rings. The meth-oxy-carbonyl group of one mol-ecule is disordered over two positions with site-occupancy factors of 0.277?(12) and 0.723?(12). Inter-molecular N-H?O hydrogen bonding is present in the crystal structure.

Dimethyl 3,3'-diphenyl-2,2'-[(S)-thio-phene-2,5-diylbis(carbonyl-aza-nedi-yl)]dipropano-ate tetra-hydro-furan monosolvate.

Project description:The title compound, C(26)H(26)N(2)O(6)S·C(4)H(8)O, a solvated bis-amide derivative, is also a chiral amino acid ester with l-phenyl-alanine methyl ester groups as amine substituents. The thio-phene-2,5-dicarboxamide core approximates C(2) point symmetry. The tetra-hydro-furan solvent mol-ecule is linked to the main mol-ecule through an inter-molecular N-H?O hydrogen bond. The central ring makes dihedral angles of 90.0?(2) and 76.5?(2)° with the pendant rings.

4,4'-[Thio-phene-2,5-diylbis(ethyne-2,1-di-yl)]dibenzonitrile.

Project description:In the solid state, the title compound, C(22)H(10)N(2)S, forms centrosymmetric dimers by pairs of non-classical C-H?S hydrogen bonds linking approximately coplanar mol-ecules. The benzene ring involved in this inter-action makes a dihedral angle of only 7.21?(16)° with the thio-phene ring, while the other benzene ring is twisted somewhat out of the plane, with a dihedral angle of 39.58?(9)°. The hydrogen-bonded dimers stack on top of each other with an inter-planar spacing of 3.44?Å. C-H?N hydrogen bonds link together stacks that run in approximately perpendicular directions. Each mol-ecule thus inter-acts with 12 adjacent mol-ecules, five of them approaching closer than the sum of the van der Waals radii for the relevant atoms. Optimization of the inter-stack contacts contributes to the non-planarity of the mol-ecule.

Project description:The title compound, C(27)H(27)N(3)O(6), a bis-amide derivative, is also a chiral amino acid ester with l-phenyl-alanine methyl ester groups as amine substituents.

(2Z,2'Z)-Diethyl 3,3'-[butane-1,4-diylbis(aza-nedi-yl)]bis-(but-2-enoate).

Project description:The whole mol-ecule of the title ?-enamino-ester, C(16)H(28)N(2)O(4), is generated by a crystallographic inversion center, situated at the mid-point of the central C-C bond of the 1,4-diamino-butane segment. There are two intra-molecular N-H?O hydrogen bonds that generate S(6) ring motifs. This leads to the Z conformation about the C=C bonds [1.3756?(17)?Å]. The mol-ecule is S-shaped with the planar central 1,4-diamino-butane segment [maximum deviation for non H-atoms = 0.0058?(13)?Å] being inclined to the ethyl butyl-enonate fragment [C-C-O-C-C=C-C; maximum deviation = 0.0710?(12)?Å] by 15.56?(10)°. In the crystal, mol-ecules are linked via C-H?O inter-actions, leading to the formation of an undulating two-dimensional network lying parallel to the bc plane.

Diethyl 3,4-dimethyl-thieno[2,3-b]thio-phene-2,5-dicarboxyl-ate.

Project description:In the title compound, C14H16O4S2, the thieno[2,3-b]thio-phene ring systems are planar [maximum deviation = 0.008 (2) Å].

Thio-phene-2-carbonyl azide.

Project description:The title compound, C5H3N3OS, is almost planar (r.m.s. deviation for the ten non-H atoms = 0.018?Å) and forms an extended layer structure in the (100) plane, held together via hydrogen-bonding inter-actions between adjacent mol-ecules. Of particular note is the occurrence of RC-H?N(-)=N(+)=NR inter-actions between an aromatic C-H group and an azide moiety which, in conjunction with a complementary C-H?O=C inter-action, forms a nine-membered ring.
