2-(9H-Fluoren-9-yl)-4-(4-fluoro-anilino)-4-oxo-butanoic acid.

ABSTRACT: 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 ?-system of the carbonyl group. In the crystal, a three-dimensional network is formed through N-H?O and O-H?O hydrogen bonds between the amide and carb-oxy-lic acid groups and carbonyl O-atom acceptors.

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 three-dimensional network is formed through N-H⋯O and O-H⋯O hydrogen bonds between the amide and carb-oxy-l ...[more]

4-(3-Fluoro-4-methyl-anilino)-2-methyl-idene-4-oxo-butanoic acid.

Project description:The title compound, C12H12FNO3, crystallizes with two independent mol-ecules (A and B) in the asymmetric unit. The dihedral angle between the mean planes of the 3-fluoro-4-methyl-phenyl ring and the oxo-amine group is 25.7?(7)° in mol-ecule A and 71.3?(7)° in mol-ecule B, while the mean plane of the 2-methyl-idene-4-oxo-butanoic acid group is twisted by 76.2?(1)° from that of the oxo-amine group in mol-ecule A and by 76.2?(4)° in mol-ecule B. In the crystal, N-H?O and O-H?O hydrogen bonds [the latter forming an R 2 (2)(8) graph-set motif] link the mol-ecules into a two-dimensional network parallel to the ac plane.

4-[(2-Fluoro-phen-yl)amino]-4-oxo-butanoic acid.

Project description:The crystal structure of the title compound, C(10)H(10)FNO(3), contains dimers of the asymmetric unit, with R(2) (2)(8) rings arising from inter-molecular O-H?O hydrogen bonding through the carboxyl-ate groups. Adjacent dimeric units are connected to each other through one N-H?O and two C-H?O inter-molecular hydrogen bonds. C-H?O hydrogen bonds involving the aromatic ring and the O atoms of two carboxyl-ate groups form an R(3) (3)(7) ring. The crystal structure is further stabilized by C-H?F inter-actions, giving rise to a three-dimensional network.

(9H-Fluoren-9-yl)(phen-yl)phosphinic acid.

Project description:The crystal structure of the title compound, C19H15O2P, features pairs of mol-ecules joined by O-H?O hydrogen bonds across crystallographic inversion centers. In addition, ?-? inter-actions, with a centroid-centroid distance of 3.6273?(9)?Å between the fluorene ring systems, connect the dimers into chains along [01-1]. The three rings make dihedral angles of 1.34?(9), 1.52?(10) and 1.51?(7)° with each other.

4-(4-Iodo-anilino)-2-methyl-ene-4-oxo-butanoic acid.

Project description:In the title compound, C11H10INO3, an addition product of itaconic acid anhydride and 4-iodo-aniline, the least-squares planes defined by the atoms of the aromatic moiety and the non-H atoms of the carb-oxy-lic acid group enclose an angle of 74.82?(11)°. In the crystal, classical O-H?O hydrogen bonds formed by carb-oxy-lic groups, as well as N-H?O hydrogen bonds formed by amide groups, are present along with C-H?O contacts. Together, these connect the mol-ecules into dimeric chains along the b-axis direction.

9-Chloro-methyl-9-[(9H-fluoren-9-yl)meth-yl]-9H-fluorene.

Project description:In the title compound, C(28)H(21)Cl, the dihedral angle between the two fluorene ring systems is 71.97?(4)°. There is an intra-molecular C-H?Cl hydrogen bond. In the crystal structure, the centroid-to-centroid distance between stacked fluorene ring systems is ca 4.22?Å, which indicates that there are no ?-? stacking inter-actions between them.

2-(9H-Fluoren-9-ylidenemeth-yl)thio-phene.

Project description:The title compound, C(18)H(12)S, contains a thio-phene ring which is disordered by rotation of 180° about the linking C-C bond. The site occupancies of the major and minor components of the disordered ring are 0.900 (3) and 0.100 (3), respectively. In one of these disordered components, the mol-ecule is stabilized by an intra-molecular C-H⋯S hydrogen bond. The compound was synthesized in good yield (80%) by a modified phase-transfer-catalysed condensation of fluorene with thio-phene-2-carbaldehyde.

4-[(4-Acetyl-phen-yl)amino]-2-methyl-idene-4-oxo-butanoic acid.

Project description:In the title compound, C13H13NO4, the N-C(=O) bond length of 1.354?(2)?Å is indicative of amide-type resonance.

In the crystal, classical O-H?O hydrogen bonds formed by the carb-oxy-lic acid groups and weak N-H?O weak inter-actions formed by the amide groups and supported by weak C-H?O inter-actions between the 2-methyl-idene, phenyl and acetyl groups with the carb-oxy-lic acid, oxo-amine and acetyl O atoms, together link the mol-ecules into dimeric chains along [010]. The O-H?O hydrogen bonds form R 2 (2)(8) graph-set motifs.
