N-Methyl-1-oxoisoindoline-2-carboxamide monohydrate

The title compound, C(10)H(10)N(2)O(2)·H(2)O, is dimerized by inversion-related inter­molecular N—H⋯O hydrogen bonding. There is an intra­molecular N—H⋯O bond, resulting in a six-membered ring. Each dimer inter­acts with other dimers through hydrogen bonding with water mol­ecules. The water mol­ecules are linked to each other in a stair-like chain, thus generating two-dimensional polymeric strips. The dimers are also linked to each other through inter­molecular C—H⋯O hydrogen bonding. There are π–π inter­actions between the aromatic and heterocyclic five-membered rings [centroid–centroid distance 3.8360 (12) Å]. C—H⋯π inter­actions also exist between CH(2) groups and aromatic rings.
