2-(3-Oxo-1,3-dihydro-isobenzofuran-1-yl)-phthalazin-1(2H)-one.

ABSTRACT: The reaction of 2-carboxy-benzaldehyde and hydrazine hydrate unexpectedly yielded the title compound, C(16)H(10)N(2)O(3), which comprises one phthalide ring, one phthalazine system and a chiral centre. The phthalide unit is almost perpendicular to the phthalazine system, forming a dihedral angle of 87.1?(3)°. The packing is governed by weak C-H?O hydrogen-bonding inter-actions, forming layers parallel to the ab plane.

Hydro-nium (3-oxo-1-phosphono-1,3-dihydro-isobenzofuran-1-yl)phospho-nate.

Project description:In the title compound, H(3)O(+)·C(8)H(7)O(8)P(2) (-), the anions form inversion dimmers by way of pairs of O-H?O hydrogen bonds involving the phospho-nic functions and via the hydro-nium cation. Further O-H?O links involving the hydronium cation play a prominant part in the cohesion of the crystal structure by building bridges between bis-phospho-nate pairs, forming infinite ribbons along the b-axis direction and by cross-linking these ribbons perpendicularly along the a-axis direction, forming an infinite three-dimensional hydrogen-bond network. The benzene ring and the C=O atoms of the furan ring are disordered over two sets of positions of equal occupancy.

2-(3-Oxo-1,3-dihydro-isobenzofuran-1-ylamino)benzoic acid.

Project description: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 N-H⋯O hydrogen bonds link the mol-ecules, generating centrosymmetric R(2) (2)(8) and R(2) (2)(11) ring motifs and forming a three-dimensional network.

Project description:The organic molecule in the title hydrate, C(9)H(9)N(3)O(3)·H(2)O, was obtained by the condenstation of salicylic aldehyde with urea in acetonitrile.

(2E)-2-[(2H-1,3-Benzodioxol-5-yl)methyl-idene]-2,3-dihydro-1H-inden-1-one.

Project description:In the title compound, C(17)H(12)O(3), each of the five-membered rings in the inden-1-one and 1,3-benzodioxole residues is almost planar (r.m.s. deviations = 0.041 and 0.033 Å, respectively). A small twist about the single bond linking the two residues is evident [the C-C-C-C torsion angle = 8.7 (4)°]. Supra-molecular zigzag layers propagating in the ac plane are formed in the crystal via C-H⋯O inter-actions. The layers are linked via π-π inter-actions between the five- and six-membered rings of 1,3-benzodioxole residues [centroid-centroid distance = 3.4977 (14) Å].

In the crystal, mol-ecules are linked through inter-molecular O-H⋯O and C-H⋯O hydrogen bonds, forming a three-dimensional network.

Phthalazin-1(2H)-one-picric acid (1/1).

Project description:The geometric parameters of the title compound, C(8)H(6)N(2)O·C(6)H(3)N(3)O(7), are in the usual ranges.
