4,4'-Dibromo-2,2'-{[(3aS,7aS)-2,3,3a,4,5,6,7,7a-octa-hydro-1H-1,3-benzimidazole-1,3-di-yl]bis-(methyl-idene)}diphenol.


ABSTRACT: The cyclo-hexane ring in the title compound, C(21)H(24)Br(2)N(2)O(2), adopts a chair conformation and the five-membered ring to which it is fused has a twisted envelope conformation. The asymmetric unit contains one half-mol-ecule, which is related to the other half by a twofold rotation axis. The two N atoms of the five-membered ring are linked to the hy-droxy groups by intra-molecular O-H?N hydrogen bonds. In the crystal, inter-molecular C-H?O and C-H?? inter-actions occur.

The cyclo-hexane ring in the title compound, C(21)H(24)Br(2)N(2)O(2), adopts a chair conformation and the five-membered ring to which it is fused has a twisted envelope conformation. The asymmetric unit contains one half-mol-ecule, which is related to the other half by a twofold rotation axis. The two N atoms of the five-membered ring are linked to the hy-droxy groups by intra-molecular O-H⋯N hydrogen bonds. In the crystal, inter-molecular C-H⋯O and C-H⋯π inter-actions occur. ...[more]
