(4-Methoxybenzoylmethyl)triphenylphosphonium trifluoromethanesulfonate
Kazem Karami,Orhan Büyükgüngr
Acta Crystallographica Section E , 2009, DOI: 10.1107/s1600536809000919
Abstract: Colourless crystals of the title compound, C27H24O2P+·CF3SO3 , have been prepared by the addition of a solution of AgCF3SO3 in methanol to a solution of (4-methoxybenzoylmethyl)triphenylphosphonium bromide in dry methanol. There are two crystallographically independent molecules in the asymmetric unit. The crystal structure is stabilized by inter- and intramolecular C—H...O hydrogen bonds and further stabilized by C—H...π interactions.
5,6-Dichloro-2-(3-methoxyphenyl)isoindoline-1,3-dione
Orhan Büyükgüngr,Mustafa Odaba?o?lu
Acta Crystallographica Section E , 2008, DOI: 10.1107/s1600536808010659
Abstract: The title compound, C15H9Cl2NO3, crystallizes as an inversion twin, the ratio of the twin components being 0.43 (13):0.57 (13). The isoindoline group is planar and inclined by 77.63 (3)° to the aromatic ring substituent. The crystal structure is stabilized by aromatic π–π stacking interactions involving the benzene rings of adjacent isoindoline groups, with a centroid–centroid distance of 3.664 (7) and an interplanar separation of 3.409 .

Acta Crystallographica Section E , 2008, DOI: 10.1107/s1600536808008891
Abstract: The crystal structure of the title salt, C6H7FN+·C8H5FNO3 , exhibits intramolecular N—H...O and C—H...O and intermolecular N—H...O and N—H...F hydrogen-bond interactions, the intramolecular hydrogen-bond interactions generating S(6) and S(5) ring motifs. The dihedral angles between the aromatic ring and the intramolecular hydrogen-bonded rings in the anion are 2.97 (7) and 6.70 (5)°. The two aromatic rings of the title compound are oriented with a dihedral angle of 77.25 (9)°.
2-(2-Hydroxyethyl)phthalazin-1(2H)-one
Orhan Büyükgüngr,Mustafa Odaba?o?lu
Acta Crystallographica Section E , 2008, DOI: 10.1107/s1600536808007691
Abstract: In the molecule of the title compound, C10H10N2O2, the rings are nearly coplanar, making a dihedral angle of 2.35 (5)°. In the crystal structure, intermolecular C—H...O, C—H...N and O—H...O hydrogen bonds link the molecules, generating R44(22) and R44(24) ring motifs to form a three-dimensional network. A weak π–π interaction between the pyridazinone and benzene rings further stabilizes the crystal structure, with a centroid–centroid distance of 3.709 (3) and an interplanar separation of 3.312 .

Acta Crystallographica Section E , 2008, DOI: 10.1107/s1600536808008209
Abstract: In the molecule of the title compound, C13H16N2O2, the phthalide ring system is virtually planar, with a dihedral angle between the fused five- and six-membered rings of 1.17 (4)°. The methylpiperazine ring adopts a chair conformation. In the crystal structure, intermolecular C—H...O and C—H...N hydrogen bonds link the molecules, generating edge-fused R33(17) ring motifs, to form a three-dimensional network.

Abstract: In the molecule of the title compound, C14H9Cl2NO2, the essentially planar phthalide group is oriented at a dihedral angle of 63.23 (5)° with respect to the substituted aromatic ring. In the crystal structure, intermolecular C—H...O and N—H...O hydrogen bonds link the molecules, generating R44(21) ring motifs to form a three-dimensional network.

Acta Crystallographica Section E , 2008, DOI: 10.1107/s1600536808010544
Abstract: The crystal structure of the title compound, C14H6Cl2FNO2, exhibits C—H...π and π–π interactions, which generate C(3) chains in the [100] direction. The π–π interaction occurs between the aromatic rings of isoindoline units, with a centroid–centroid distance of 3.672 and an interplanar separation of 3.528 . The isoindoline unit is planar and inclined at an angle of 58.63 (18)° to the substituent benzene ring. The F atom is disordered over two positions, with refined occupancies of 0.669 (3) and 0.331 (3).

Abstract: In the molecule of the title compound, C14H7Cl2NO3, the phthalimide ring system is virtually planar, with a dihedral angle between the fused five- and six-membered rings of 4.02 (3)°. In the crystal structure, intermolecular C—H...O and O—H...O hydrogen bonds and C—Cl...O close contacts [Cl...O = 3.0123 (13) and C—Cl...O = 171.14 (7)°] link the molecules, generating R22(16), R42(19) and R44(22) ring motifs by C(6) chains to form a three-dimensional network. A weak π–π interaction between the six-membered rings of the phthalimide ring systems further stabilizes the structure, with a centroid–centroid distance of 3.666 (3) and an interplanar separation of 3.568 .
