(4-Chloro-phen-yl)(3,6-dibromo-2-hy-droxy-7-meth-oxy-1-naphth-yl)methanone.

ABSTRACT: The asymmetric unit of the title compound, C(18)H(11)Br(2)ClO(3), contains two crystallographically independent mol-ecules in which the dihedral angles between the naphthalene ring systems and the benzene rings are 55.64?(11) and 60.50?(11)°. In each mol-ecule, an intra-molecular O-H?O=C hydrogen bond generates a six-membered ring. In the crystal structure, inter-molecular C-H?O and C-H?Cl hydrogen bonds and two different Br?O halogen bonds [2.9850?(19) and 3.2169?(19)?Å] are observed.

Crystal structure of [4-(chloro-meth-yl)phen-yl](4-hy-droxy-piperidin-1-yl)methanone.

Project description:The title compound, C13H16ClNO2, crystallized with two independent mol-ecules in the asymmetric unit (A and B). The piperidinol ring in mol-ecule B is disordered over two positions with a site occupancy ratio of 0.667 (5):0.333 (5). In both mol-ecules these rings have a chair conformation, including the minor component in mol-ecule B. Their mean planes are inclined to the benzene ring by 45.57 (13)° in mol-ecule A, and by 50.5 (4)° for the major component of the piperidine ring in mol-ecule B. In the crystal, the individual mol-ecules are linked by O-H⋯O hydrogen bonds, forming chains of A and B mol-ecules along the [100] direction. The chains are inter-linked by C-H⋯O hydrogen bonds, forming ribbons.

[2-(2-Meth-oxy-1-naphtho-yl)phen-yl](1-naphth-yl)methanone.

Project description:The title compound, C(29)H(20)O(3), adopts an 'S' conformation with a dihedral angle of 68.5 (2)° beween the two acetone planes.
