(R)-2'-Benz-yloxy-5,5',6,6',7,7',8,8'-octa-hydro-1,1'-binaphthyl-2-ol.


ABSTRACT: The mol-ecules of the title compound, C(27)H(28)O(2), exhibit axial chirality. The planes of the aromatic rings of the tetra-lin ring systems make an angle of 85.72?(11)°. The non-aromatic rings adopt distorted half-chair conformations. In one of them, two C atoms of the four-atom aliphatic chain are disordered over two sites in a 0.75?(2):0.25?(2) ratio. The substituent phenyl ring is also disordered over two positions in a 0.59?(3):0.41?(3) ratio. There are no conventional hydrogen bonds joining the mol-ecules.
