Phenyl acridine-9-carboxylate
The acridine ring system and the benzene ring in the title compound, C(20)H(13)NO(2), are oriented at a dihedral angle of 6.4 (2)°. The carboxyl group is twisted at an angle of 83.6 (2)° relative to the acridine skeleton. The mol-ecules in the crystal are arranged in stacks along the b axis, with two of the acridine rings involved in multiple π-π inter-actions [centroid-centroid distances in th...
متن کامل9-Phenyl-10H-acridinium trifluoromethanesulfonate
In the crystal structure of the title compound, C(19)H(14)N(+)·CF(3)SO(3) (-), the cations are linked to each other by very weak C-H⋯π inter-actions, while the cations and anions are connected by N-H⋯O, C-H⋯O and S-O⋯π inter-actions. The acridine ring system and the phenyl ring are oriented at an angle of 80.1 (1)° with respect to each other. The mean planes of adjacent acridine units are eithe...
متن کامل(1S*,5R*)-9-Phenyl-9-azabicyclo[3.3.1]nonan-3-one
In the title compound, C(14)H(17)NO, the piperidinone and piperidine rings both adopt a chair conformation. The chiral crystals were obtained from a racemic reaction product via spontaneous resolution.
متن کامل9-Phenyl-4,5-diaza-9H-fluoren-9-ol monohydrate
The title compound, C(17)H(12)N(2)O·H(2)O, was synthesized by the reaction of 4,5-diaza-fluoren-9-one with a Grignard reagent in ether (the reaction mixture being hydrolysed with saturated NH(4)Cl solution), and crystallizes with two organic mol-ecules and two water mol-ecules in the asymmetric unit. The 4,5-diaza-fluorene fragment is approximately planar, with r.m.s. deviations of 0.0448 and 0...
متن کاملHippokrates Ueber die Krankheiten III
irrelevant. Chemistry and the relations between science, technology, and industry are well surveyed by Crosland and Cardwell respectively. Forbes's essay on mathematical cosmography is not a comprehensive account but the story (albeit interesting) of a few German cartographers. Compared with other recent collections of essays in the history of science, this volume parades no party line: witness...
