(Z)-1-(2,5-Dichloro-3-thienyl)ethanone semicarbazone
The title mol-ecule, C(7)H(7)Cl(2)N(3)OS, is approximately planar [maximum deviation = 0.062 (1) Å]. Short inter-molecular distances between the centroids of the five-membered rings [3.5340 (8) Å] indicate the existence of π-π inter-actions. An inter-esting feature of the crystal structure is the presence of short intra-molecular Cl⋯N inter-actions [3.0015 (11) Å]. Mol-ecules are linked via pai...
متن کامل(Z)-1,2-Dichloro-1,2-bis(3-chloroquinoxalin-2-yl)ethene
The title compound, C(18)H(8)Cl(4)N(4), exists in a cis configuration with respect to the bridging C=C bond. The two essentially planar quinoxaline ring systems [maximum deviations = 0.012 (1) and 0.022 (1) Å] are inclined at an angle of 59.84 (3). In the crystal, adjacent mol-ecules are linked into chains propagating along [001] via inter-molecular C-H⋯N hydrogen bonds. Weak inter-molecular π-...

In the title compound, C(9)H(11)N(3)O, the benzene ring is disordered over two positions with refined occupancies of 0.922 (5) and 0.078 (5). The program PLATON [Spek (2009 ▶). Acta Cryst. D65, 148-155] recommends the solution in the space group C2/m with a = 7.3050 (3), b = 6.6745 (2), c = 18.3853 (6) Å and β = 96.986 (2)°. However, the large number of non-extinct reflections needed to be igno...
متن کامل4-[(1E)-3-(2,6-Dichloro-3-fluorophenyl)-3-oxoprop-1-en-1-yl]benzonitrile
In the title mol-ecule, C(16)H(8)Cl(2)FNO, the benzene rings form a dihedral angle of 78.69 (8)°. The F atom is disordered over two positions in a 0.530 (3):0.470 (3) ratio. The crystal packing exhibits π-π inter-actions between dichloro-substituted rings [centroid-centroid distance = 3.6671 (10) Å] and weak inter-molecular C-H⋯F contacts.
متن کامل2,6-Dichloro-3-nitropyridine
The asymmetric unit of the title compound, C(5)H(2)Cl(2)N(2)O(2), consists of two crystallographically independent mol-ecules. The pyridine ring in each mol-ecule is essentially planar, with maximum deviations of 0.004 (4) and 0.007 (4) Å. Short Cl⋯O [3.09 (3) and 3.13 (4) Å] and Cl⋯Cl [3.38 (12) Å] contacts were observed. No significant inter-molecular inter-actions were observed in the crysta...
