3-{1-[2-(2-Chloro­phen­yl)hydrazinyl­idene]-2,2,2-trifluoro­eth­yl}-7-diethyl­amino-2H-chromen-2-one

The title compound, C(21)H(19)ClF(3)N(3)O(2), has a structure related to other coumarin derivatives that have been used as fluorescent probes of metal ions. The dihedral angle between the coumarin ring system and the chlorobenzene ring is 42.99 (9)°. Intra­molecular hydrogen bonding occurs via N—H⋯O...

description The title compound, C(21)H(19)ClF(3)N(3)O(2), has a structure related to other coumarin derivatives that have been used as fluorescent probes of metal ions. The dihedral angle between the coumarin ring system and the chlorobenzene ring is 42.99 (9)°. Intra­molecular hydrogen bonding occurs via N—H⋯O and N—H⋯Cl inter­actions, generating S(7) and S(5) rings, respectively. The crystal packing is stabilized by weak C—H⋯O hydrogen bonds.
