Structural, Thermodynamic and Kinetic (Hysteresis) Aspects of the Enantiotropic First-Order Phase Transformations of N-Anilinophthalimide and N-(N'-Methylanilino)phthalimide
Autor: N. Gasper, F.H. Herbstein, A. Ellern, M. Botoshansky, J.-O. Henck
Publikováno v: Acta Crystallographica Section B Structural Science. 54:277-290
The crystal structures of the orthorhombic and monoclinic polymorphs of N-anilinophthalimide (m.p. of monoclinic polymorph 457 K) have been determined by X-ray diffraction at 293 K and were found to have only small differences between the molecular c

Ethyl 3,3-Dimethyl-2-(1-oxo-3-phenylinden-2-yl)acrylate
Autor: S. Goldberg, M. Botoshansky, M. Kaftory, Y. Goldberg
Publikováno v: Acta Crystallographica Section C Crystal Structure Communications. 54:849-851
The crystal structure of the title compound, C22H20O3, was determined from intensities collected at 120 K. The dihedral angle between the phenyl ring and the indenone moiety is 124.6 (1)°. The non-bonded distance between the potentially reacting cen

Publikováno v: Acta Crystallographica Section C Crystal Structure Communications. 53:1907-1909
The title azulene, C 17 H 10 BrN, (I), and ester, C 26 H 16 O 4 , (II), are precursors for the preparation of the corresponding 1,8a-dihydroazulenes which are potentially photochromic compounds. In both compounds, the azulene moiety is found to be pl

2-p-Cyanophenyl-1,8a-dihydroazulene-1,1-dicarbonitrile and Methyl 1-Cyano-2-p-cyanophenyl-1,8a-dihydroazulene-1-carboxylate
Autor: Jörg Daub, A. Bross, C. Fischer, M. Kaftory, M. Botoshansky
Publikováno v: Acta Crystallographica Section C Crystal Structure Communications. 53:1665-1667
The title compounds, C 19 H 11 N 3 and C 20 H 14 N 2 O 2 , show solid-state photochromic properties. In both compounds, the dihydroazulene moiety was found to adopt the boat conformation.
