Meso-3,6-Dioxopiperazine-2,5-diacet-amide.

ABSTRACT: The title compound, C(8)H(12)N(4)O(4), was obtained by cyclization of the two l-asparagine mol-ecules and reveals a crystallographic inversion symmetry, and accordingly the two stereogenic centres are of opposite chirality. Thus, an asymmetric unit comprises a half of a mol-ecule. The mol-ecules are assembled into a three-dimensional hydrogen-bonding network by N-H?O hydrogen bonds.

N,N'-Dibenzyl-2,2'-[(1,3,4-oxadiazole-2,5-di-yl)bis-(o-phenyl-eneoxy)]diacet-amide.

Project description:The compound, C(32)H(28)N(4)O(5), which was synthesized by the reaction of 2,5-bis-(2-hydroxy-lphen-yl)-1,3,4-oxadiazole with N-benzyl-2-chloro-acetamide, lies on a twofold rotation axis which passes through the mid-point of the N-N bond and the O atom of the oxadiazole unit. The phenyl-ene and oxadiazole rings are almost coplanar [dihedral angle 1.67?(5)°]. The structure is stabilized by intra-molecular N-H?O and N-H?N hydrogen bonds.

2,5-Dichloro-3,6-diisopropyl-cyclo-hexa-2,5-diene-1,4-dione.

Project description:The mol-ecule of the title compound, C(12)H(14)Cl(2)O(2), lies about an inversion center. The six-membered ring is almost planar, with the largest deviation from the least-squares plane being 0.014?(4)?Å. The mol-ecular conformation is stabilized by a weak intra-molecular C-H?O hydrogen bond. In the crystal, mol-ecules are packed into stacks along the c-axis direction, with an inter-centroid separation of 4.811?(2)?Å. Neighboring mol-ecules within the stack are related by the c-glide plane.

2,5-Di-bromo-3,6-dimeth-oxycyclo-hexa-2,5-diene-1,4-dione.

Project description:In the structure of the title compound, C8H6Br2O4, the complete mol-ecule is generated by the application of a centre of inversion. The mol-ecule is planar (r.m.s. deviation for all non-H atoms but methyl C = 0.0358?Å), with only the methyl groups being deviated from the plane [by ±0.321?(4)?Å]. In the crystal packing, Br?O(methoxy) halogen bonds [3.2407?(19)?Å] connect molecules into supramolecular layers parallel to (101).

meso-Dimethyl 2,5-dibromo-hexa-ne-dioate.

Project description:The title compound, C(8)H(12)Br(2)O(4), lies about a crystallographic center of inversion at the midpoint of the central C-C bond. The latter is also repsonsible for the observation of the meso form. There are no intra-molecular hydrogen bonds, but mol-ecules are connected by inter-molecular C-H?O inter-actions, forming a three-dimensional network.

Diethyl trans-2,5-bis-(4-methoxy-benzyl-sulfan-yl)-1,4-dimethyl-3,6-dioxopiperazine-2,5-carboxyl-ate.

Project description:The title compound, C(28)H(34)N(2)O(8)S(2), was synthesized as part of a project to develop synthetic routes to analogues of sporidesmins, a class of secondary metabolite produced by the filamentous fungi Chaetomium and Pithomyces sp. The complete molecule is generated by crystallographic inversion symmetry: the methoxy group is essentially coplanar with the benzene ring to which it is bonded, a mean plane fitted through the non-H atoms of the aromatic ring and the meth-oxy group having an r.m.s. deviation of 0.0140?Å. Similarly, the ester group is also essentially planar (r.m.s. deviation of a plane fitted through all non-H atoms is 0.0101?Å). There is only one independent C-H?O inter-action, which links together adjacent mol-ecules into a two-dimensional sheet in the bc plane.

Three differently coloured polymorphs of 3,6-bis(4-chlorophenyl)-2,5-dipropyl-2,5-dihydropyrrolo[3,4-c]pyrrole-1,4-dione.

Project description:In this paper, the conformational polymorphism of a chlorinated diketopyrrolopyrrole (DPP) dye having flexible substituents in a non-hydrogen-bonding system is reported. The propyl-substituted DPP derivative (PR3C) has three polymorphic forms, each showing a different colour (red, orange and yellow). All polymorphs could be obtained concomitantly under various crystallization conditions. The results of the crystal structure analysis indicate that PR3C adopts different conformations in each polymorph. The packing effect caused by the difference in the arrangement of neighbouring molecules was found to play an important role in the occurrence of the observed polymorphism. The thermodynamic stability relationship between the three polymorphs was identified by thermal analysis and indicates that the yellow polymorph is the thermally stable form. The results indicate that the yellow form and orange form are enantiotropically related, and the other polymorph is monotropically related to the others.

2,5-Bis[4-(dimethyl-amino)-phen-yl]-3,6-dimethyl-pyrazine.

Project description:The title compound, C(22)H(26)N(4), was prepared from p-dimethyl-amino-propiophenone in six steps. The mol-ecule has no crystallographic symmetry. The dihedral angles between the pyrazine ring and the phenyl rings are 35.81?(6) and 37.11?(8)°. The dimethyl-amino groups are essentially planar (sum of the bond angles at N = 359.3 and 359.9°) and nearly coplanar with the adjacent aromatic ring [dihedral angles = 5.54?(11) and 7.40?(3)°]. This effect and the short aniline C-N bonds can be rationalised in terms of charge transfer from the amino groups to the central pyrazine ring.

Cyclo-hexa-2,5-diene-1,4-dione-1,2,4,5-tetra-fluoro-3,6-diiodo-benzene (1/1).

Project description:The asymmetric unit of the title co-crystal adduct, C(6)H(4)O(2)·C(6)F(4)I(2), comprises a half-mol-ecule each of cyclo-hexa-2,5-diene-1,4-dione and 1,2,4,5-tetra-fluoro-3,6-diiodo-benzene. The C(6)F(4)I(2) mol-ecule is almost planar (r.m.s. deviation = 0.0062?Å). In the crystal, the components are connected through O?I halogen bonds [3.017?(11)?Å], leading to the formation of wavelike chains along the a axis. The crystal packing also features C-H?F inter-actions.

2,5-Dihexyl-3,6-diphenyl-pyrrolo-[3,4-c]pyrrole-1,4(2H,5H)-dione.

Project description:The asymmetric unit of the title compound, C(30)H(36)N(2)O(2), contains one half-mol-ecule, the other half being generated by a crystallographic inversion centre. The crystal structure is devoid of any classical hydrogen bonds however, non-classical C-H?O inter-actions link the mol-ecules into chains propagating in [001] and a C-H?? inter-action leads to the formation of a two-dimensional network in (011).

Tetra-aqua-(1,10-phenanthroline)nickel(II) 3,6-dicarboxy-bicyclo-[2.2.2]oct-7-ene-2,5-dicarboxyl-ate.

Project description:In the title compound, [Ni(C(12)H(8)N(2))(H(2)O)(4)](C(12)H(10)O(8)), the Ni(II) ion is six-coordinated by two N atoms from one phenanthroline ligand and by the O atoms of four water mol-ecules in a distorted octa-hedral geometry. In the crystal, inter-molecular O-H?O hydrogen bonds form an extensive three-dimensional network, which consolidates the crystal packing.
