2-[(E)-(2-Hy-droxy-naphthalen-1-yl)methyl-idene-amino]-isoindoline-1,3-dione.

ABSTRACT: The title compound, C(19)H(12)N(2)O(3), has two independent mol-ecules (A and B) in the asymmetric unit. There is an intra-molecular O-H?N hydrogen bond in each mol-ecule. The mean planes of the naphthalene [maximum deviations = 0.024?(3) and 0.030?(3)?Å in A and B, respectively] and the isoindoline units [maximum deviations 0.009?(3) and 0.008?(3)?Å in A and B, respectively] are almostly coplanar, with dihedral angles of 4.25?(9) ad 3.84?(9)° in mol-ecules A and B, respectively. The two independent mol-ecules are connected by ?-? inter-actions [centroid-centroid distances 3.5527?(19) and 3.5627?(19)?Å]. In the crystal, the A+B pairs are further connected via ?-? inter-actions [centroid-centroid distances = 3.693?(2)-3.831?(2)?Å], leading to the formation of columns propagating along the a-axis direction. The columns are linked via C-H?O inter-actions, leading to the formation of a three-dimensional network.
