Naphthalene-2,6-dicarboxylic acid–1-methylpyrrolidin-2-one (1/2)

Naphthalene-2,6-dicarb­oxy­lic acid–1-methyl­pyrrolidin-2-one (1/2)

The asymmetric unit of the title compound, C(12)H(8)O(4)·2C(5)H(9)NO, contains one half-mol-ecule of naphthalene-2,6-dicarb-oxy-lic acid (NDA) and one mol-ecule of 1-methyl-pyrrolidin-2-one (NMP): the NDA molecules lie on the crystallographic twofold rotation axes. In the crystal, the components are linked by strong O-H⋯O hydrogen bonds and C-H⋯O inter-actions.

Phenyl naphthalene-2-sulfonate

In the crystal structure of the title compound, C(16)H(12)O(3)S, the dihedral angle between the naphthalene ring system and the phenyl ring is 65.21 (3)°. The mol-ecules are linked by inter-molecular C-H⋯O hydrogen bonds, forming a chain along the a axis. The chains are connected through weak C-H⋯π inter-actions.

2-(3-Oxo-1,3-dihydro­isobenzofuran-1-ylamino)benzoic acid1

In the mol-ecule of the title compound, C(15)H(11)NO(4), the essentially planar phthalide group is oriented at a dihedral angle of 56.78 (5)° with respect to the substituted aromatic ring. An intra-molecular N-H⋯O hydrogen bond results in the formation of a non-planar six-membered ring, which adopts a nearly flattened-boat conformation. In the crystal structure, inter-molecular C-H⋯O, O-H⋯O and...
