چکیده
In the crystal of the title compound, C19H14N4O4, the asymmetric unit consists of two discrete mol-ecules. The C=N bonds in both mol-ecules show an E conformation. The dihedral angles between the C atoms of the 2,4-dinitrobenzene rings and the C=N-N planes are 13.52 (9) and 13.82 (9)° for the two mol-ecules. In the crystal, C-H⋯O hydrogen bonds, mainly between the phenyl ring and the nitro group along the b axis.

Crystal structure of (E)-1-(2-nitrobenzylidene)-2,2-diphenylhydrazine
The title compound, C19H15N3O2, shows an E conformation of the imine bond. The dihedral angle between the planes of the phenyl rings in the di-phenyl-hydrazine groups is 88.52 (4)°. The 2-nitro-benzene ring shows a torsion angle of 10.17 (8)° with the C=N-N plane. A short intra-molecular C-H⋯O contact occurs. In the crystal, only van der Waals contacts occur between the mol-ecules.

In the title compound, [Ni(C(14)H(8)O(5))(C(10)H(8)N(2))](n), the Ni(II) atom is six-coordinated in a slightly distorted octa-hedral geometry by four O atoms from two chelating carboxyl-ate groups of symmetry-related 2,4'-oxydibenzoate anions and by two N atoms from a 2,2'-bipyridine ligand. The Ni(II) atoms are bridged by the 2,4'-oxydibenzoate anions, resulting in the formation of helical cha...

It is shown that the Veldkamp space of the unique generalized quadrangle GQ(2,4) is isomorphic to PG(5,2). Since the GQ(2,4) features only two kinds of geometric hyperplanes, namely point’s perp-sets and GQ(2,2)s, the 63 points of PG(5,2) split into two families; 27 being represented by perp-sets and 36 by GQ(2,2)s. The 651 lines of PG(5,2) are found to fall into four distinct classes: in parti...

In the title compound, [Co(C(8)H(5)Cl(2)O(3))(C(12)H(12)N(2))], the Co(II) atom, lying on a twofold rotation axis, is coordinated by four O atoms from two chelating 2,4-dichloro-phen-oxy-acetate ligands and two N atoms from a 5,5'-dimethyl-2,2'-bipyridine ligand, displaying a distorted octa-hedral geometry. A three-dimensional supra-molecular structure is formed through inter-molecular C-H⋯O hy...

The title compound, C(19)H(18)Cl(2)O(8), was prepared by the reaction of 2,2-dimethyl-1,3-dioxane-4,6-dione and 2,4-dichloro-benzaldehyde in ethanol. The two 1,3-dioxane rings exhibit boat conformations. In the crystal, mol-ecules are linked by weak inter-molecular C-H⋯O and C-H⋯Cl hydrogen bonds, forming chains parallel to the a axis.
