3-(7,8,13,14-Tetra-hydrodi-benzo-[a,i]phen-an-thridin-5-yl)benzene-1,2-diol.

ABSTRACT: In the title compound, C(27)H(21)NO(2), the half-chair conformation of the alicyclic rings gives rise to a slightly folded structure of the central tricyclic tetra-hydrophenanthridine unit. Tandem intra-molecular O-H?N and O-H?O hydrogen bonds give rise to adjacent S(6) and S(5) rings, respectively, which dictate the conformation of the 5-aryl substituent. In the crystal structure, an inter-molecular C-H?O contact generates chains parallel to [101]. Short O-H?? and C-H?? contacts are also observed.

In the title compound, C(27)H(21)NO(2), the half-chair conformation of the alicyclic rings gives rise to a slightly folded structure of the central tricyclic tetra-hydrophenanthridine unit. Tandem intra-molecular O-H⋯N and O-H⋯O hydrogen bonds give rise to adjacent S(6) and S(5) rings, respectively, which dictate the conformation of the 5-aryl substituent. In the crystal structure, an inter-molecular C-H⋯O contact generates chains parallel to [101]. Short O-H⋯π and C-H⋯π contacts are also observ ...[more]

Project description:The title compound, C15H12F3NO3, crystallizes with one mol-ecule in the asymmetric unit.
