ABSTRACT: In the title compound, C(22)H(13)ClN(2), the quinoxaline ring system is close to planar [maximum deviation = 0.061?(2)?Å]. The phenyl ring at the 2-position and the phenyl ring of the phenyl-ethynyl substituent make dihedral angles of 49.32?(7) and 11.99?(7) °, respectively, with the quinoxaline mean plane. The two phenyl rings are inclined to one another by 61.27?(9)°. In the crystal, mol-ecules are linked by C-H?? and ?-? inter-actions [centroid-centroid distances = 3.6210?(12) and 3.8091?(12)?Å].

In the title compound, C(22)H(13)ClN(2), the quinoxaline ring system is close to planar [maximum deviation = 0.061 (2) Å]. The phenyl ring at the 2-position and the phenyl ring of the phenyl-ethynyl substituent make dihedral angles of 49.32 (7) and 11.99 (7) °, respectively, with the quinoxaline mean plane. The two phenyl rings are inclined to one another by 61.27 (9)°.

Project description:In the title compound, [Co(C(13)H(9))(C(28)H(20))], the Co atom is sandwiched between cyclo-penta-dienyl and cyclo-butadienyl rings that are inclined at a dihedral angle of 2.6?(3)°. The four phenyl rings are tilted with respect to the cyclo-butadienyl plane so that the C(4)Ph(4) unit constitutes a four-bladed propeller. The phenyl ring of the phenyl-alkyne substituent is inclined to the cyclo-penta-dienyl ring at an angle of 34.92?(18)°. The crystal structure is stabilized solely by C-H?? inter-actions which generate a three-dimensional network.

Project description:In the centrosymmetric title compound, C(64)H(62)N(4), the two phenyl-ethynyl groups lie at diagonal meso positions. The 24-membered porphyrin has in-plane distortion with respect to the mean plane of the macrocycle and two intra-ring bifurcated N-H?(N,N) hydrogen bonds occur. The dihedral angles between the phenyl rings in the phenyl-ethynyl group and the 3,5-bis-(tert-but-yl)phenyl group with respect to the mean plane of the porphyrin are 17.2?(2) and 59.2?(3)°.

1-Ethyl-2-phenyl-3-[2-(tri-methyl-sil-yl)ethyn-yl]-1H-indole.

Project description:The title compound, C21H23NSi, was synthesized by Sonogashira-type reaction of 1-ethyl-3-iodo-2-phenyl-1H-indole with tri-methyl-silyl-acetyl-ene. The indole ring system is nearly planar [maximum atomic deviation = 0.0244?(15)?Å] and is oriented at a dihedral angle of 51.48?(4)° with respect to the phenyl ring. The supramolecular aggregation is completed by weak C-H?? inter-actions of the methylene and phenyl groups with the benzene and pyrrole rings of the indole ring system. The methyl groups of the tri-methyl-silyl unit are equally disordered over two sets of sites.

rac-(2R,3S)-2-Phenyl-3-(3-phenyl-1,2,3,4-tetra-hydro-quinoxalin-2-yl)quinoxaline.

Project description:The title compound, C(28)H(22)N(4), is the unexpected by-product of the reaction of 2-hydroxy-acetophenone and 1,2-diamino-benzene under iodine catalysis, during which a carbon-carbon ?-bond between two quinoxaline units was formed. Although a fully oxidized title compound should sterically be possible, only one quinoxaline ring is fully oxidized while the second ring remains in the reduced form. As expected, the tetra-hydro-quinoxaline unit is not planar; it adopts a sofa conformation, whereby the atom joining the two heterocyclic systems lies out of the plane of the other atoms. The quinoxaline ring system makes a dihedral angle of 53.61?(4)° with its phenyl ring substituent. The crystal packing is determined by pairs of N-H?N, N-H?? and weak C-H?N hydrogen bonds, forming a chain parallel to the a axis.

2-[(E)-2-(3,4-Di-chloro-benzyl-idene)hydrazin-1-yl]quinoxaline.

Project description:The 21 non-H atoms of the title compound, C15H10Cl2N4, are almost planar (r.m.s. deviation = 0.032 Å); the conformation about the N=C bond [1.277 (6) Å] is E. In the crystal, zigzag supra-molecular chains along the c axis (glide symmetry) are formed via N-H⋯N hydrogen bonds. These associate along the b axis by π-π inter-actions between the fused and terminal benzene rings [inter-centroid distance = 3.602 (3) Å] so that layers form in the bc plane.

Bis[4-(chloro-acet-yl)phenyl] ether.

Project description:The title compound, C(16)H(12)Cl(2)O(3), crystallizes with two independent mol-ecules in the asymmetric unit. The dihedral angles between the planes of the benzene rings in the two independent mol-ecules are 68.65?(2) and 68.47?(3)°. The short distance of 3.899?(5)?Å between the centroids of the benzene rings of neighbouring mol-ecules indicate ?-? inter-actions. The crystal structure is stabilized by a network of intermolecular C-H?O hydrogen bonds.
