2,2′-Diazinodimethylidyne)di-o-phenylene) dibenzoate

چکیده
The title compound, C(28)H(20)N(2)O(4), was synthesized by the reaction of 2-(hydrazonometh-yl)phenyl benzoate with iodine. The mol-ecule possesses a crystallographically imposed center of symmetry at the mid-point of the hydrazine N-N bond. The substituents at the ends of the C=N bonds adopt an E,E configuration. Inter-molecular C-H⋯π(arene) hydrogen bonds and aromatic π-π stacking inter-actions [centroid-centroid distance 3.900 (1) Å] link the mol-ecules into (100) sheets. In addition, there is an inter-molecular C-H⋯O hydrogen-bond inter-action.

The V-shaped propeller-like mol-ecule of the title compound, C(29)H(24)O(4), does not exhibit crystallographic twofold symmetry as the two benzene rings are twisted asymmetrically with respect to both the central propyl plane and the benzo-yloxy groups [4.6 (2), 43.6 (2)° and 45.07 (8), 69.50 (8)°]. In the crystal structure, centrosymmetrically related mol-ecules form a dimer through C-H⋯π inte...

The title coordination polymer, {[Co(C(18)H(14)O(4))(C(10)H(8)N(2))]·0.5H(2)O}(n), features a helical polymeric chain that runs along the b axis. The Co atoms are chelated by the carboxyl-ate groups of two 3,3'-(but-2-ene-2,3-di-yl)dibenzoate ligands and the N atoms of a 2,2'-bipyridine ligand. The lattice water mol-ecule is disordered about a center of inversion and is connected to the chain b...

In the title compound, K(+)·C(14)H(9)O(4)S(2) (-)·C(14)H(10)O(4)S(2), the hydrogen 2,2'-dithio-dibenzoate and 2,2'-disulfane-diyl-di-ben-zoic acid species combine to provide an O(6)S(2) donor set to the potassium cation based on a cubic geometry. K⋯S [3.1733 (7) and 3.5499 (8) Å] and K⋯O [2.6586 (16)-3.0661 (15) Å)] inter-actions, coupled with O-H⋯O hydrogen bonding, lead to the formation of su...

The centrosymmetric title mol-ecule, C(28)H(32)N(2)O(2), has a central benzene ring subsituted in the 1- and 4-positions by (ethene-2,1-di-yl)pyridine groups, and in the 2- and 5-positions by but-oxy groups. The whole mol-ecule is X-shaped and relatively flat, the dihedral angle between the pyridine and the central benzene ring being 11.29 (10)°. In the crystal, neighboring mol-ecules are linke...
