چکیده
The mol-ecular structure of the title compound, [Fe(C(5)H(5))(C(13)H(9)N(2))], (I), is analogous to that of the compound (Z)-3-ferrocenyl-2-phenyl-acrylonitrile [Cao & Ye (2008). Acta Cryst. E64, m822], (II), with the pyridine ring in (I) replacing the benzene ring in (II). While the corresponding bond distances and angles in the two compounds show no significant differences, the two dihedral angles between the planes through the acrylonitrile group and the two rings attached to it (substituted Cp and pyridine) of 16.8 (4) and 20.1 (4)° in (I) are different from the corresponding dihedral angles [19.6 (3) and 6.5 (4)°] in (II). The unsubstituted ring is disordered over two positions, with site-occupancy factors of 0.70 (1) and 0.30 (1). The major and minor components of the disordered ring are almost coplanar and are also parallel to the substituted cyclo-penta-diene ring plane, with a dihedral angle of 0.3 (6)°.

The title compound, [Fe(2)(C(5)H(5))(2)(C(30)H(22)N(2)O(2))], a 2:1 product of the reaction of 2-ferrocenylbenzoic acid and 2-amino-4-methyl-pyridine, forms a twisted mol-ecular structure in the solid state due to steric effects from the two benzene rings ortho-substituted with ferrocenyl and carbonyl-derived groups. A short intra-molecular C-H⋯π interaction is observed involving a substituted ...

The title compound, C(23)H(16)N(2)O(3), exists in a Z configuration with respect to the acyclic C=C bond. The pyridine and phenyl rings are oriented at dihedral angles of 72.97 (4) and 45.05 (4)°, respectively, with respect to the almost planar indoline ring system [maximum deviation 0.080 (1) Å]. The pyridine and phenyl rings are oriented almost perpendicular to each other [dihedral angle 88.9...
متن کاملVisible-light photochromism of triarylamine- or ferrocene-bound diethynylethenes that switches electronic communication between redox sites and luminescence.
Redox-active ferrocene- and triarylamine-terminated diethynylethene derivatives have been synthesized and their photochromic properties and switching behavior based on through-bond electronic communication between the two redox sites, as well as their emissions, have been examined. Both bis(ferrocenylethynyl)ethene 1 and bis(triarylaminoethynyl)ethene 2 show visible-light photochromism induced ...
