In the title compound, C(13)H(8)Br(2)N(2)O(6), the 2-furyl ring is essentially planar, with a maximum deviation of 0.002 (2) Å. It is inclined at an angle of 33.94 (9)° to the benzene ring. Both nitro groups are slightly twisted away from their attached rings; the dihedral angles are 4.6 (2)° between the nitro group and the 2-furyl ring, and 13.72 (19)° between the nitro group and the benzene r...

In the title compound, C(13)H(8)Br(2)ClNO(4), the linking -CHBr-CHBr- fragment is disordered over two orientations with refined site occupancies of 0.512 (11) and 0.488 (11). The dihedral angle between the furan ring and the phenyl ring is 21.86 (16)°. In the crystal, the mol-ecules are linked into [011] chains by inter-molecular C-H⋯O hydrogen bonds.

In the title compound, C(17)H(11)Br(3)N(2)O(3), the whole mol-ecule is disordered over two positions with a refined occupancy ratio of 0.770 (5):0.230 (5). In the major component, the 1,2,3-oxadiazo-lidine ring is essentially planar [maximum deviation = 0.017 (6) Å] and makes dihedral angles of 22.5 (3) and 70.2 (3)° with the 4-bromo-phenyl and phenyl rings, respectively. In the minor component...

The title compound, C(20)H(20)Br(2)ClN(3)O(3), was synthesized by the condensation reaction of 2-chloro-5-nitro-benzaldehyde with 4-(2-amino-3,5-dibromo-benzyl-amino)cyclo-hexa-nol in a methanol solution. There are two independent mol-ecules in the asymmetric unit and in one mol-ecule the atoms of the cyclo-hexane ring are disordered over two sets of sites with refined occupancies of 0.657 (12)...
