Hydrogen-bonded chains of rings linked by iodo-carbonyl inter­actions in 5-iodo­isatin and hydrogen-bonded sheets in 7-trifluoro­methyl­isatin

In 5‐iodo­isatin (5‐iodo‐1H‐indole‐2,3‐dione), C8H4INO2, the mol­ecules are linked into chains of rings by N—H⋯O and C—H⋯O hydrogen bonds, and these chains are linked into sheets by iodo–carbonyl inter­actions. In 7‐trifluoro­methyl­isatin (7‐trifluoro­methyl‐1H‐indole‐2,3‐dione), C9H4F3NO2, the mol...

Description
Summary:In 5‐iodo­isatin (5‐iodo‐1H‐indole‐2,3‐dione), C8H4INO2, the mol­ecules are linked into chains of rings by N—H⋯O and C—H⋯O hydrogen bonds, and these chains are linked into sheets by iodo–carbonyl inter­actions. In 7‐trifluoro­methyl­isatin (7‐trifluoro­methyl‐1H‐indole‐2,3‐dione), C9H4F3NO2, the mol­ecules are linked into sheets of centrosymmetric R22(8) and R66(34) rings by N—H⋯O and C—H⋯O hydrogen bonds.
