چکیده
In the title compound, C17H12N2O3, the mean planes of the benzene ring and the quinoline moiety are inclined to one another by 11.0 (1)°. The nitro substituent is twisted at an angle of 7.9 (2)° with respect to the attached benzene ring. Intra-molecular O-H⋯N and C-H⋯N hydrogen bonds occur. The crystal is constructed of mol-ecular stacks without involvement of π-stacking inter-actions, but showing inter-stack association via O-H⋯O and C-H⋯O hydrogen bonding. Thus, the supramolecular architecture of the crystal results from stacked molecules stabilized by hydrogen bonding between the stacks.

The title compound, [Ag(C(9)H(7)NO)(2)](C(7)H(3)N(2)O(7)), was prepared from 3,5-dinitro-salicylic acid (DNS), quinolin-8-ol and AgNO(3). The Ag(I) atom is coordinated by two N atoms and two O atoms from two quinolin-8-ols in a roughly planar [maximum deviation = 0.223 (2) Å] environment. The two quinolin-8-ol ligands are bent slightly with respect to each other, making a dihedral angle of 9.55...
