title: 2-Hydr-oxy-3,3-dimethyl-7-nitro-3,4-dihydro-isoquinolin-1(2H)-one.
abstract: In the title compound, C(11)H(12)N(2)O(4), a new hydroxamic acid which belonging to the isoquinole family, the heterocyclic ring adopts a half-chair conformation. The nitro group is essentially coplanar with the aromatic ring. Inter-molecular O-H⋯O hydrogen bonds assemble the mol-ecules around inversion centres to form pseudo-dimers.
