2-(9H-Fluoren-9-yl)-4-(4-fluoroanilino)-4-oxobutanoic acid
In the title compound, C23H18FNO3, the tricyclic 9-fluorenyl system is approximately planar (r.m.s. deviation = 0.0279 Å). The N-C(=O) bond length is comparatively short [1.359 (3) Å], which is typical for such conjugated systems. The N atom has a planar configuration [sum of bond angles= 359.8°] due to conjugation of its lone pair with the π-system of the carbonyl group. In the crystal, a thre...
متن کاملN-(9H-Fluoren-9-ylidene)-4-methylaniline
In the title compound, C(20)H(15)N, the fluorene unit is essentially planar [r.m.s. deviation 0.0334 Å] and the benzene ring bound to the imine N atom bears a methyl group which is nearly coplanar [dihedral angle 0.5 (1)°]. The dihedral angle between the substituent benzene ring and the 9H-fluoren-9-imine unit is 71.1 (3)°. Inter-molecular π-π inter-actions between the benzene rings of adjacent...
متن کامل2-Dibutylamino-1-(2,7-dichloro-9H-fluoren-4-yl)ethanol
In the title compound, C(23)H(29)Cl(2)NO, the fluorene ring is essentially planar, with a maximum deviation from the mean plane of 0.041 (1) Å. The amine group adopts a pyramidal configuration, the sum of the bond angles being 336.2 (3)°. In the crystal, the mol-ecules are linked into dimers by inter-molecular O-H⋯N and C-H⋯O hydrogen bonds. Weak C-H⋯π and π-π [centroid-centroid distance = 3.75...
متن کامل4-Allylmorpholin-4-ium bromide
The title compound, C(7)H(14)NO(+)·Br(-), was formed by reaction of 4-allyl-morpholine and hydrogen bromide. In the crystal, mol-ecules are connected via N-H⋯Br and C-H⋯Br hydrogen bonds, forming a three-dimensional network.
متن کامل(2R)-4-[(9H-Fluoren-9-ylmethoxy)carbonyl]-2-methylpiperazin-1-ium chloride
The synthesis of the title salt, C(20)H(23)N(2)O(2) (+)·Cl(-), was carried out with a precursor of known absolute configuration (R) and the X-ray analysis confirmed that the product retained the absolute configuration. In the crystal, the dominant packing motif is a chain running along [010] generated by N-H⋯Cl hydrogen bonding. C-H⋯O and C-H⋯Cl inter-actions are also observed.
