2,2'-(1,3,5,7-Tetra-oxo-1,2,3,5,6,7-hexa-hydro-pyrrolo[3,4-f]isoindole-2,6-di-yl)diacetic acid N,N-dimethyl-formamide disolvate.

ABSTRACT: The asymmetric unit of the title compound, C(14)H(8)N(2)O(8)·2C(3)H(7)NO or L·2DMF (DMF = N,N-dimethyl-formamide), contains one half of the centrosymmetric mol-ecule L and one solvent mol-ecule, which is disordered between two orientations in a 0.555?(4):0.445?(4) ratio. Inter-molecular O-H?O hydrogen bonds link one L and two DMF mol-ecules into a centrosymmetric hydrogen-bonded cluster. The crystal packing is further stabilized by weak inter-molecular C-H?O hydrogen bonds.

Crystal structure of 2,6-di-benzyl-pyrrolo-[3,4-f]iso-indole-1,3,5,7(2H,6H)-tetra-thione.

Project description:The title compound, C24H16N2S4, consists of a central pyromellitic di-imide substituted with an S atom and terminal benzyl groups. The mol-ecule lies on a crystallographic inversion centre so that the asymmetric unit contains half of the mol-ecule. The mol-ecule was prepared by thio-nation of N,N'-di-benzyl-pyromellitic di-imide with Lawesson's reagent and has an S-shaped conformation similar to other compounds of this type. The phenyl groups are tilted by 72.69 (8)° with respect to the plane of the central arene ring. In the crystal, mol-ecules are connected by C-H⋯π inter-actions and weak short S⋯S contacts, forming supra-molecular layers extending paralled to the ab plane. The crystal studied was found to be non-merohedrally twinned, with the minor component being 0.113 (3).

Project description:In the title compound, [Ni(C(19)H(13)N(5))(2)](C(6)H(2)N(3)O(7))(2)·2C(3)H(7)NO, the Ni(II) ion is coordinated by two tridentate 2,6-bis-(1H-benzimidazol-2-yl)pyridine ligands in a distorted octa-hedral geometry.

Further stabilization is provided by weak inter-molecular C-H⋯O hydrogen bonds. One of the DMF moleclues is disordered over two sites with refined occupancies of 0.737 (3) and 0.263 (3).

Methyl (9aR*,10S*,11R*,13aS*,13bS*)-9-oxo-6,7,9,9a,10,11-hexa-hydro-5H,13bH-11,13a-ep-oxy-pyrrolo-[2',1':3,4][1,4]diazepino[2,1-a]isoindole-10-carboxyl-ate.

Project description:The title compound, C(17)H(18)N(2)O(4), is the methyl ester of the adduct of intra-molecular Diels-Alder reaction between maleic anhydride and 1-(2-fur-yl)-2,3,4,5-tetra-hydro-1H-pyrrolo-[1,2-a][1,4]diazepine. The mol-ecule comprises a fused penta-cyclic system containing four five-membered rings (viz. pyrrole, 2-pyrrolidinone, tetra-hydro-furan and dihydro-furan) and one seven-membered ring (1,4-diazepane). The pyrrole ring is approximately planar (r.m.s. deviation = 0.003 Å) while the 2-pyrrolidinone, tetra-hydro-furan and dihydro-furan five-membered rings have the usual envelope conformations. The central seven-membered diazepane ring adopts a boat conformation. In the crystal, mol-ecules are bound by weak inter-molecular C-H⋯O hydrogen-bonding inter-actions into zigzag chains propagating in [010]. In the crystal packing, the chains are stacked along the a axis.

Ethyl 1-benzyl-1,2,3,3a,4,10b-hexa-hydro-pyrrolo-[2',3':3,4]pyrrolo-[1,2-a]benzimidazole-2-carboxyl-ate.

Project description:The title mol-ecule, C(22)H(23)N(3)O(2), was obtained via an intra-molecular cyclo-addition of an azomethine ylide and an alkene tethered by a benzimidazole unit. The benzoimidazole unit is essentially planar, with an r.m.s. deviation of 0.0087 Å from the nine constituent atoms. It has a cis fusion of the two pyrrolidine rings as well as a cis ester appendage. The two pyrrolidine rings rings have envelope conformations. The crystal packing is stabilized by aromatic π-π stacking of parallel benzimidazole ring systems, with a centroid-to-centroid distance of 3.518 (6) Å. Weak inter-molecular C-H⋯O contacts may also play a role in the stability of the packing.
