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)
In the title compound, C(13)H(10)N(2)O(2), a Schiff base derivative, the dihedral angle between the two aromatic rings is 31.58 (3)°. The C=N double bond is essentially coplanar with the nitro-phenyl ring. The torsion angle of the imine double bond is 175.97 (13)°, indicating that the C=N double bond is in a trans configuration. The crystal structure is… (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)
Mol-ecules of the title compound, C(20)H(14)O(2), show approximate C(s) symmetry with the approximate mirror plane perpendicular to the central ring. The torsion angles about the acyclic bonds are 30.05 (15) and 30.77 (15)° in one half compared to -36.62 (14) and -18.60 (15)° in the other half of the mol-ecule. The central aromatic ring makes dihedral… (More)
The aim of this work is to derive the results for random coincidence points for multivalued nonlinear contractions in partially ordered metric spaces. We do it from two different approaches, the first is -symmetric property and the second is by using g-mixed monotone property. These results are the random versions of Hussain and Alotabi [Fixed Point Theory… (More)
The crystal structure of the title compound, C(10)H(13)NO(4), features inter-molecular O-H⋯O(nitro) hydrogen bonding, which links mol-ecules into supra-molecular chains running parallel to the bc diagonal. There is also π-π stacking between 4-nitro-phenyl groups, the inter-planar distance between the nitro-benzene rings being 3.472 (2) Å.
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 two phenyl rings of the biphenyl unit of the title compound, C(18)H(13)NO(3), are almost coplanar [dihedral angle 6.70 (9)°]. The nitro-phenyl ring, on the other hand, is significantly twisted out of the plane of the these two rings, making dihedral angles of 68.83 (4)° with the middle ring and 62.86 (4)° with the end ring. The nitro group is twisted by… (More)
In the title compound, C(27)H(16)F(6)N(2)O(6), the nitro groups are almost coplanar with the aromatic rings to which they are attached [dihedral angles = 3.5 (5) and 6.2 (3)°]. The dihedral angles between adjacent aromatic rings are 78.07 (8) and 71.11 (8)° for nitro-phen-yl/phenyl and 69.50 (8)° for phen-yl/phenyl. An inter-molecular C-H⋯π inter-action… (More)
In the title compound, C(19)H(16)N(2)O(3)S·C(2)H(6)O, the 4-hy-droxy-benzyl-idene group is oriented at dihedral angles of 73.17 (7) and 77.06 (7)° with respect to the aniline groups. The sulfonyl group make dihedral angles of 44.89 (13) and 59.16 (12)° with the adjacent aniline groups. In the crystal, a two-dimensional polymeric network parallel to (010) is… (More)
