چکیده
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.

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...
