5-Benzoyl-13-bromo-4-hydroxy[2.2]paracyclophane
The title compound, C(23)H(19)BrO(2), was synthesized from 13-bromo-4-hy-droxy[2.2]paracyclo-phane and benzoyl chloride. The hy-droxy and carbonyl groups are involved in intra-molecular O-H⋯O hydrogen bonding. The crystal packing exhibits weak C-H⋯O inter-actions, which link the mol-ecules into sheets parallel to the bc plane.

In the title mol-ecule, C(17)H(13)FN(2)O(2), the 3,4-dihydro-pyrimidine ring adopts a flattened sofa conformation with the flap atom (which bears the fluoro-phenyl substituent) deviating from the plane defined by the remaining five ring atoms by 0.281 (2) Å. This plane forms dihedral angles of 85.98 (6) and 60.63 (6)° with the 4-fluoro-phenyl and benzoyl-phenyl rings, respectively. The dihedral...

In the title compound, C4H3BrClN3, the pyrimidine ring is essentially planar (r.m.s. deviation from the plane = 0.087 Å). In the crystal, pairs of N-H⋯N hydrogen bonds connect the mol-ecules into inversion dimers; these are connected by further N-H⋯N hydrogen bonds into a two-dimensional framework parallel to the bc plane.

In the title mol-ecule, C(15)H(12)BrClO(2), the two benzene rings form a dihedral angle of 69.30 (3)°. In the crystal structure, weak inter-molecular C-H⋯O hydrogen bonds link mol-ecules into chains propagating along the b axis.
متن کاملN′-(5-Bromo-2-hydroxybenzylidene)-4-chlorobenzohydrazide
The title Schiff base, C(14)H(10)BrClN(2)O(2), exists in a trans configuration with respect to the C=N bond and the dihedral angle between the two benzene rings is 0.8 (2)°. There is an intra-molecular O-H⋯N hydrogen bond in the mol-ecule, which generates an S(6) loop. In the crystal, inter-molecular N-H⋯O hydrogen bonds link adjacent mol-ecules into extended chains propagating along the c-axis...
