Crystal structure of N,N'-di-benzyl-pyromellitic diimide.

ABSTRACT: The title compound, C₂₄H₁₆N₂O₄ [systematic name: 2,6-di-benzyl-pyrrolo-[3,4-f]iso-indole-1,3,5,7(2H,6H)-tetra-one], consists of a central pyromellitic di-imide moiety with terminal benzyl groups at the N-atom positions. The mol-ecule is located about an inversion centre, so the asymmetric unit contains one half-mol-ecule. In the mol-ecule, both terminal phenyl groups, tilted by 72.97?(4)° with respect to the mean plane of the central pyromellitic di-imide moiety (r.m.s. deviation = 0.0145?Å), are oriented away from each other, forming an elongated S-shaped conformation. In the crystal, mol-ecules are connected via weak C-H?O hydrogen bonds and C-H?? inter-actions, resulting in the formation of supra-molecular layers extending parallel to the ab plane.

Crystal structure of N,N'-di-decyl-pyromellitic di-imide.

Project description:The title compound, C30H44N2O4 [systematic name: 2,6-di-decyl-pyrrolo-[3,4-f]iso-indole-1,3,5,7(2H,6H)-tetra-one], consists of a central pyromellitic di-imide moiety with terminal decyl groups at the N-atom positions. The centre of the mol-ecule lies on a crystallographic inversion centre so the asymmetric unit contains one half-mol-ecule. The mol-ecule exhibits a rod-shaped conformation, like other similar compounds of this type, the distance between the ends of terminal decyl groups being 32.45 Å. The packing is dominated by a lamellar arrangement of the mol-ecules, which is reinforced by C-H⋯O hydrogen bonds and C-O⋯π inter-actions, forming a classic herringbone structure. The mol-ecular structure is consistent with the theoretical calculations performed by density functional theory (DFT).

Crystal structure of di-benzyl-dimethyl-silane.

Project description:In the title compound, C16H20Si, a geometry different from an ideal tetra-hedron can be observed at the Si atom. The bonds from Si to the benzylic C atoms [Si-C = 1.884 (1) and 1.883 (1) Å] are slightly elongated compared to the Si-Cmeth-yl bonds [Si-C = 1.856 (1) and 1.853 (1) Å]. The Cbenz-yl-Si-Cbenz-yl bond angle [C-Si-C = 107.60 (6)°] is decreased from the ideal tetra-hedral angle by 1.9°. These distortions can be explained easily by Bent's rule. In the crystal, mol-ecules inter-act only by van der Waals forces.

Crystal structure of catena-poly[1,3-di-benzyl-benzimidazolium [[chlorido-mercurate(II)]-di-?-chlorido]].

Project description:The asymmetric unit of the polymeric title compound, {(C21H19N2)[HgCl3]} n , comprises one-half of the cationic mol-ecule, the other half being generated by application of twofold rotation symmetry, one Hg and two Cl atoms. The Hg(II) atom, lying on a twofold rotation axis, exhibits a distorted triangular coordination environment and is surrounded by three Cl atoms with Hg-Cl distances in the range 2.359?(2)-2.4754?(13)?Å. Two additional longer distances [Hg?Cl = 3.104?(14)?Å] lead to the formation of polymeric [HgCl1/1Cl4/2](-) chains extending along [001]. The crystal packing can be described by cationic layers alternating parallel to (-110) with the anionic chains located between the layers. The packing is consolidated by ?-? stacking inter-actions between the benzene rings of the central benzimidazole entities, with centroid-to-centroid distances of 3.643?(3)?Å.

Crystal structure of benzyl 3-(3-methyl-phen-yl)di-thio-carbazate.

Project description:In the title compound, C15H16N2S2, the central CN2S2 residue is almost planar (r.m.s. deviation = 0.0354 Å) and forms dihedral angles of 56.02 (4) and 75.52 (4)° with the phenyl and tolyl rings, respectively; the dihedral angle between the aromatic rings is 81.72 (5)°. The conformation about the N-N bond is gauche [C-N-N-C = -117.48 (15)°]. Overall, the mol-ecule has the shape of the letter L. In the crystal packing, supra-molecular chains along the a axis are formed by N-H⋯S(thione) hydrogen bonds whereby the thione S atom accepts two such bonds. The hydrogen bonding leads to alternating edge-shared eight-membered {⋯HNCS}2 and 10-membered {⋯HNNH⋯S}2 synthons. The chains are connected into layers by phen-yl-tolyl C-H⋯π inter-actions; the layers stack along the c axis with no specific inter-actions between them.

Crystal structure of benzyl (E)-2-(3,4-di-meth-oxy-benzyl-idene)hydrazine-1-carbodi-thio-ate.

Project description:The title compound, C17H18N2O2S2, synthesized via a condensation reaction between S-benzyl di-thio-carbazate and 3,4-di-meth-oxy-benzaldehyde, crystallized with two independent mol-ecules (A and B) in the asymmetric unit. Both mol-ecules have an L-shape but differ in the orientation of the benzyl ring with respect to the 3,4-di-meth-oxy-benzyl-idine ring, this dihedral angle is 65.59?(8)° in mol-ecule A and 73.10?(8)° in mol-ecule B. In the crystal, the A and B mol-ecules are linked via pairs of N-H?S hydrogen bonds, forming dimers with an R 2 (2)(8) ring motif. The dimers are linked via pairs of C-H?O hydrogen bonds, giving inversion dimers of dimers. These units are linked by C-H?? inter-actions, forming ribbons propagating in the [100] direction.

Optical and Electrochemical Properties of a Photosensitive Pyromellitic Diimide Derivative of Cymantrene.

Project description:Photochemical properties of symmetrical pyromellitic diimide containing two cymantrenyl fragments at two nitrogen atoms were studied with IR, NMR, UV-vis, ESI-MS, and cyclic voltammetry. It was found that new unstable chelates are formed during photolysis. At the same time, the CO ligand dissociates from two Mn(CO)3 fragments during photoexcitation, which dramatically changes the electronic and redox properties of the molecule compared to the cymantrene derivative containing one imide fragment. Photolysis leads to a color change from light yellow to green. DFT calculations confirmed the possibility of the formation of complexes due to the loss of one or two CO ligands from manganese atoms. The results obtained with variation of photolysis conditions demonstrated the hemilabile character of the Mn-O=C(imide) bond. On addition of external ligands, the color and electrochemical properties changed, which is promising for the use of this complex as a sensor for small molecules.

In the crystal, mol-ecules are linked by bifurcated C-H,H?O hydrogen bonds, forming layers parallel to the ac plane. The layers are linked by C-H?? inter-actions, forming a supra-molecular three-dimensional structure.

Crystal structure of N'-[4-(di-methyl-amino)-benzyl-idene]furan-2-carbohydrazide monohydrate.

Project description:The condensation of 2-furoic hydrazide and 4-dimethyl amino-benzaldehyde in ethanol yielded a yellow solid formulated as the title compound, C14H15N3O2·H2O. The crystal packing is stabilized by inter-molecular O(water)-H?O,N(carbohydrazide) and N-H?O(water) hydrogen bonds, which form a two-dimensional network along the bc plane. Additional C-H?O inter-actions link the mol-ecules into a three-dimensional network. The dihedral angle between the mean planes of the benzene and the furan ring is 34.47?(6)°. The carbohydrazide moiety, i.e., the C=N-N-C=O fragment and the benzene ring are almost coplanar, with an angle of 6.75?(9)° between their mean planes.
