The title compound, C23H15F6NS2 is a new non-symmetric photochromic dithienylethene. The mol­ecule adopts a photoactive anti­parallel conformation, the distance between the two reactive C atoms being 3.552 (6) Å. The dihedral angles between the cyclo­pentene ring and the two thio­phene rings are 44.0 (5) and 45.8 (5)°. [ABSTRACT FROM AUTHOR]

In the title compound, C19H18N2O2, the dihedral angles made by the central pyrazole ring with the benzyl and phenyl rings are 87.00 (9) and 15.23 (9)°, respectively. There is a short intermolecular interaction between a C—H bond and the benzyl ring. [ABSTRACT FROM AUTHOR]

In the title compound, C21H21ClN2O2, the pyrazole and chlorobenzene rings are coplanar and make a dihedral angle of 79.7 (2)° with the tert-butylbenzene ring. The crystal structure displays intermolecular O—H...O hydrogen bonding. [ABSTRACT FROM AUTHOR]

In the structure of the title compound, C17H16O5, the dihydrofuran ring adopts an envelope conformation while the methylenedioxyphenyl ring system is essentially planar. The vinyl group is inclined to the dihydrofuran ring by 30.22 (12)°. The dihedral angle between the atoms defining the planar part of the dihydrofuran ring and the aryl ring is 19.12 (8)° [ABSTRACT FROM AUTHOR]

In the title structure, C23H25ClN2O2, there are weak intramolecular C—H...N and C—H...O hydrogen bonds. There is a C=O... Cg interaction ( Cg is the centroid of the pyrazole ring) and the distance between the centroids of the ring and the C=O bond is 3.017 (3) Å. The angle between the pyrazole ring and the chlorophenyl ring is 12.85 (13)°. The crystal packing is stabilized mainly by van der Waals forces. [ABSTRACT FROM AUTHOR]

In the title compound, C19H17ClN2O2, all non-H atoms except for the benzyl substituent are coplanar to within 0.044 Å. [ABSTRACT FROM AUTHOR]

In the structure of the title compound, [Fe(C5H5)(C13H14BrN2O2)], the two cyclopentadienyl (Cp) rings are in an eclipsed conformation and are parallel. The dihedral angle between the substituted Cp ring and the heterocyclic ring is 8.20°. [ABSTRACT FROM AUTHOR]

In the title compound, C16H12ClN3O2, the pyrazole ring makes dihedral angles of 4.6 (1) and 67.1 (1)° with the phenyl and pyridine rings, respectively. The structure displays O—H...N hydrogen bonding. [ABSTRACT FROM AUTHOR]
