Subjects
Crystallography, QD901-999
Abstract

In the title compound, C9H8Br2O, the cyclopentene ring adopts an envelope conformation with the brominated C atom as the flap. In the crystal, molecules are linked by strong O—H...O hydrogen bonds into zigzag C(4) chains along [010]. In addition, a C—H...π interaction involving the benzene ring and the H atom attached to the hydroxylated C atom is observed.

Subjects
Crystallography, QD901-999
Abstract

In the title compound, C11H10Br2O2, the cyclopentene ring fused to the benzene ring adopts an envelope conformation, with the C atom attached to the Br atom as the flap. The crystal structure does not exhibit any classical hydrogen bonds. The molecular packing is stabilized by van der Waals forces and π–π stacking interactions with a centroid–centroid distance of 3.811 (4) Å.

Subjects
Crystallography, QD901-999
Abstract

In the title compound, C13H12O, the cyclopentene ring fused with the naphthalene group adopts an envelope conformation. The cyclopentene torsion angle, with the fusion bond at the centre, has a magnitude of 1.16 (16)°. In the crystal, neighbouring molecules are connected through O—H...O hydrogen bonds into an R44(8) ring motif. The crystal packing also features weak π–π stacking interactions [centroid–centroid distance = 3.8981 (8) Å] and C—H...π interactions.

4. 5-Amino-4-bromo-2,3-dihydro-1H-inden-1-one

Author

Ramazan Erenler, Ahmet Tutar, Ísmail Çelik, Makbule Yılmaz, Mehmet Akkurt, and Santiago García-Granda

Subjects
Crystallography, QD901-999
Abstract

In the title compound, C9H8BrNO, the non-H-atom framework is essentially planar, with a maximum deviation of 0.087 (3) Å. In the crystal, molecules are interconnected into a three-dimensional network by C—H...O and N—H...O hydrogen bonds. In addition, C—H...π interactions and a π–π stacking interaction, with a centroid–centroid distance of 3.5535 (19) Å, are also observed.

Abstract

In the title compound, C9H8Br2O, the cyclo-pentene ring adopts an envelope conformation with the brominated C atom as the flap. In the crystal, molecules are linked by strong O - H?O hydrogen bonds into zigzag C(4) chains along [010]. In addition, a C - H?? inter-action involving the benzene ring and the H atom attached to the hydroxy-lated C atom is observed., Çelik, Í.; Department of Physics, Faculty of Sciences, Cumhuriyet University, 58140 Sivas, Turkey; email: icelik@cumhuriyet.edu.tr

Abstract

In the title compound, C 9H 8BrNO, the non-H-atom framework is essentially planar, with a maximum deviation of 0.087 (3) Å. In the crystal, mol-ecules are inter-connected into a three-dimensional network by C - H?O and N - H?O hydrogen bonds. In addition, C - H?? inter-actions and a ?-? stacking inter-action, with a centroid-centroid distance of 3.5535 (19) Å, are also observed., Akkurt, M.; Department of Physics, Faculty of Sciences, Erciyes University, 38039 Kayseri, Turkey; email: akkurt@erciyes.edu.tr
