In the mol-ecule of the title compound, C(21)H(19)NO, the terminal saturated six-membered ring of the dihydro-acridine unit adopts an envelope conformation, while the other two fused rings are nearly coplanar, with a dihedral angle of 2.61 (3)°. The coplanar ring system is oriented with respect to the phenyl ring at a dihedral angle of 74.58 (3)°. In the crystal structure, there is a C-H⋯π cont...

In the title compound, C(14)H(8)Br(2)F(3)NO, the mol-ecule is disordered across an approximate non-crystallographic mirror plane, which is in the plane of the fused ring system [The tetrahedral C atom bearing the trifluormethyl substituent is disordered with site occupancy factors of 0.80 (2) and 0.20 (2)]. In the crystal, a one-dimensional stacking of mol-ecules involves inter-actions between ...

The title compound, C(26)H(28)O(3)Si, is an allylic oxidation product of the tert-but-yl(2,2-dimethyl-2,3-dihydro-benzo-furan-7-yl-oxy)diphenyl-silane with N-bromo-succinimide and 2,2'-azobis-isobutyronitrile. The nine-atom bicyclic system is almost planar, with an r.m.s deviation of 0.0123 (2) Å and a maximum deviation of 0.031 (2) Å for the O atom. In the crystal, the mol-ecules pile up along...

In the crystal structure of the title compound, C(11)H(13)NO(2), the mol-ecules are paired into centrosymmetric dimers via inter-molecular O-H⋯N hydrogen bonds.

There are two independent mol-ecules in the asymmetric unit of the title compound, C(15)H(13)NO(2), in both the six-membered dihydro-pyridine rings adopt a half-chair conformation. The two benzene rings make dihedral angles of 43.66 (10) and 62.22 (10)° in the two mol-ecules. In the crystal, the two independent mol-ecules are linked alternately by inter-molecular O-H⋯O hydrogen bonds, forming a...
