In the title mol-ecule, C23H29NO5, the central piperidine ring has a chair conformation. The planes of the two benzene rings are inclined each to other at 61.7 (1)°. The crystal packing exhibits no directional inter-actions only van der Waals contacts.
The title compound, C25H29Cl2NO, which is a chloro analog of 2,4-bis-(2-bromo-phen-yl)-7-(tert-pent-yl)-3-aza-bicyclo-[3.3.1]nonan-9-one [Park, Ramkumar & Parthiban (2012). Acta Cryst. E68, o2946], exists in a twin-chair conformation with an equatorial orientation of the 2-chloro-phenyl groups. The tert-pentyl group on the cyclo-hexa-none adopts an… (More)
There are two independent mol-ecules in the asymmetric unit of the title compound, C19H16N2O5S, in which the thia-zole rings make dihedral angles of 80.89 (11) and 84.81 (11)° with the pyrano[3,2-c]chromene ring systems. An intra-molecular N-H⋯O hydrogen bond involving the amino group occurs in each independent mol-ecule. In the crystal, the amino groups… (More)
In the title mol-ecular salt, C16H10NO(+)·I(-), the dihedral angle between the pyridinium and benzene rings is 6.61 (8)°. In the crystal, the cation is linked to the anion by a C-H⋯I inter-action arising from the activated aromatic C atom adjacent to the N(+) cation.
The mol-ecular structure of the title compound, C(14)H(18)Br(2)N(2)O(2), has one half-mol-ecule in the asymmetric unit. The mol-ecule has a crystallographic inversion centre in the middle of the benzene ring. The C-C-N-C torsion angle between the benzene ring and the bromo-amide group is 149.2 (7)°. The crystal is stabilized by a strong inter-molecular… (More)
The central ring of the title compound, C(28)H(32)N(2)O(3), exists in a chair conformation with an equatorial disposition of all the alkyl and aryl groups on the heterocycle. The para-anisyl groups on both sides of the secondary amino group are oriented at an angle of 54.75 (4)° with respect to each other. The oxime derivative exists as an E isomer with the… (More)
In the title compound, C(38)H(31)Cl(4)N(3)O·C(3)H(6)O, the 3,7-diaza-bicycle exists in a chair-boat conformation.

In the… (More)
The piperidin-4-one ring in the title compound, C(26)H(26)Cl(2)N(2)O, exists in a chair conformation with equatorial orientations of the methyl and 4-chlorophenyl groups. The C atom bonded to the oxime group is statistically planar (bond-angle sum = 360.0°) although the C-C=N bond angles are very different [117.83 (15) and 127.59 (15)°]. The dihedral angle… (More)
In the title compound, C(12)H(14)O(2)S(3), a chain transfer agent (CTA) used in polymerization, the dihedral angle between the aromatic ring and the CS(3) grouping is 84.20 (10)°. In the crystal, carb-oxy-lic acid inversion dimers linked by pairs of O-H⋯O hydrogen bonds generate R(2) (2)(8) loops.
