In the title mol-ecule, C(11)H(8)FNO, the dihedral angle between the pyrrole and benzene rings is 49.16 (6)°. In the crystal, adjacent mol-ecules are linked by pairs of N-H⋯O hydrogen bonds, forming inversion dimers.

Two possible isomers of some 1,3-diaryl-H-benzo[f]chromene have been studied using density functional theory. Structures of E1 and E2 isomers were optimized at the B3LYP and MP2 levels with different basis sets. The total electronic energies show that E2 isomer is about 3-5 kcal/mol more stable than E1 isomer and this energy difference is attributed to the planarity of heterocyclic ring and mor...

In the current scenario, removal of heavy metals from contaminated water has become a major challenging task to world researchers because disposal untreated into aquatic environment have adverse effect towards ecosystem. Keeping this in mind, present study investigates synthesize sugarcane bagasse biochar modified magnetic nanoparticles decontamination and their batch scale potential chromium (...

In the title compound, C15H13N3O, the pyrrolyl and phenyl rings make dihedral angles of 58.99 (5) and 34.95 (5)°, respectively, with the central pyrazole ring. In the crystal, weak, pairwise C-H⋯O inter-actions across centers of symmetry form dimers, which are further associated into corrugated sheets running approximately parallel to (100) via weak C-H⋯N inter-actions.
