Nitroaromatics i.e. 1-nitro-4-phenoxybenzene (1), 4-(4-nitrophenyloxy) biphenyl (2), 1-(4-nitrophenoxy) naphthalene (3) and 2-(4-nitrophenoxy) naphthalene (4) were synthesized by Williamson etherification and characterized by elemental analysis, FTIR, NMR ((1)H, (13)C), UV-visible spectroscopy, mass spectrometry and single crystal X-ray diffraction… (More)
Cyclic voltammetry (CV) coupled with UV-vis and fluorescence spectroscopy were used to probe the interaction of potential anticancer drug, 4-nitrophenylferrocene (NFC) with DNA. The electrostatic interaction of the positively charged NFC with the anionic phosphate of DNA was evidenced by the findings like negative formal potential shift in CV, ionic… (More)
The title compound, C(17)H(18)N(2)O(6), crystallizes with two mol-ecules in the asymmetric unit. In both molecules, one of the C-C bonds of the penta-methyl-ene chain connecting the two aromatic rings is in a trans conformation and another displays a gauche conformation. The aromatic rings within each mol-ecule are nearly coplanar [dihedral angles = 3.36… (More)
The title compound, C(18)H(16)N(2)O(2), is a precusor for the synthesis of polyimides. The mol-ecule is located on a crystallographic inversion center and the terminal amino-phen-oxy rings are almost perpendicular to the central benzene ring with a dihedral angle of 85.40 (4)°. The mol-ecular conformation is stabilized by N-H⋯O and N-H⋯N inter-molecular… (More)
In the title compound, C(17)H(11)NO(4), the dihedral angle between the two benzene rings is 8.66 (3)°. The nitro group is twisted by 4.51 (9)° out of the plane of the aromatic ring to which it is attached. The presence of inter-molecular C-H⋯O contacts in the crystal structure leads to the formation of chains along the c axis.
The complete molecule of the title compound, C(18)H(24)N(2)O(2), is generated by a crystallographic inversion centre. The torsion angles in the hexa-methyl-ene chain are consistent with an anti-periplanar conformation, whereas the conformation of the O-CH(2)-CH(2)-CH(2) unit is gauche. The three-dimensional crystal packing is stabilized by N-H⋯O and N-H⋯N… (More)
The asymmetric unit of the title compound, C(17)H(18)N(2)O(4), contains two independent mol-ecules (A and B) differing principally in the conformations of the alkyl chains, anti for molecule A and gauche for molecule B. The dihedral angles between the aromatic rings are 82.51 (6) and 82.25 (6)° in the two molecules. In the crystal, amide-amide inter-actions… (More)
In the title compound, C12H8N2O5, the aromatic rings are inclined to one another by 56.14 (7)°. The nitro groups are inclined by to the benzene rings to which they are attached by 3.86 (17) and 9.65 (15)°. In the crystal, mol-ecules are linked by C-H⋯O hydrogen bonds, forming a three-dimensional structure. The title compound is a new monoclinic polymorph,… (More)
The title compound, C(22)H(28)N(2)O(6), crystallizes with four half-mol-ecules in the asymmetric unit: each mol-ecule is located about a crystallographic inversion centre. The central methyl-ene groups of two mol-ecules are disordered over two sets of equally occupied sites. The crystal packing is characterized by sheets of mol-ecules parallel to (14).
The aromatic rings in the title compound, C13H8ClNO4, enclose a dihedral angle of 39.53 (3)°. The nitro group is almost coplanar with the ring to which it is attached [dihedral angle = 4.31 (1)°]. In the crystal, mol-ecules are connected by C-H⋯O hydrogen bonds into chains running along .
