LiAbstract: In the title structure, C21H16BrClN2, the pyrazoline ring is approximately coplanar with the N-substituted phenyl ring. The molecules are connected by two N-HO intermolecular hydrogen bonds to form helicoidal chains running parallel to the c axis. YaminAbstract: In the title compound, C13H9FN2, the dihedral angle between the benzimidazole and benzene ring systems is 29. The benzene rings of these substituents are not parallel, but are partially involved in intramolecular - stacking. So, the diferrence I saw between yahoo. There is a network of hydrogen bonds between the phenolic groups and thiocyanate anions. saved by 481 other people . It crystallizes with three molecules in the asymmetric unit. WongAbstract: The title compound, C7H6F2N2O, is an important intermediate for the synthesis of biologically active heterocyclic compounds. bibliographic record in BIBTeXEndNoteRefManReferMedlineCIFSGMLPlain Text format Find reference: Acta Cryst. In the crystal structure, molecules form planar N-HS hydrogen-bonded dimers. One intramolecular hydrogen bond influences the conformation of the molecule. This should be my decision," said Nasir, a regular customer, wearing a green turtleneck sweater and jeans. X-ray crystal structure analysis reveals that the benzene and phenyl rings form a dihedral angle of 59. The molecules are linked by intermolecular N-HN hydrogen bonds to form infinite chains parallel to the b axis. Foot and the Octopus Kidz and A day in the life of a-bit-taller-than-average-man. The crystal structure is stabilized by N-HF, C-HO and weak C-H interactions.
