Phenyl acridine-9-carboxylate

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...

9-Chloro-1-methyl-7-phenyl-5,6-dihydro-13H-indolo[3,2-c]acridine

The title compound, C(26)H(19)ClN(2), is a 5,6-dihydro-13H-indolo[3,2-c]acridine prepared by condensation of a 2,3,4,9-tetra-hydro-1H-carbazol-1-one with 2-amino-benzophenone. The crystals undergo a destructive phase change upon cooling at varying temperatures between 270 and 200 K, depending on cooling rate and disturbance by vibration, thus indicating supercooling of the metastable room-tempe...

2,6-Dimethyl­phenyl acridine-9-carboxyl­ate

In the title compound, C(22)H(17)NO(2), the acridine ring system and the benzene ring are oriented at a dihedral angle of 37.7 (1)°. The carboxyl group is twisted at an angle of 67.7 (1)° relative to the acridine skeleton. In the crystal, mol-ecules are arranged in stacks along the b axis, with all of the acridine rings involved in multiple π-π inter-actions [centroid-centroid distances in the ...

9-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...
