چکیده
In the title compound, C11H6FN3O5, the dihedral angle between the aromatic rings is 72.4 (3)°. The NO2 groups form dihedral angles of 40.8 (2) and 4.8 (2)°, respectively, with the attached pyridine and benzene rings. The crystal structure features π-π stacking between centrosymmetrically related pairs of pyridine rings [centroid-centroid separation = 3.800 (3) Å].

In the title compound, C(12)H(11)FN(4)O(2), the pyridine ring is connected to a benzene ring by a -CH(2)-NH(2)- chain. The nitro group is twisted out of the pyridine ring plane [torsion angle O-N-C-C = 10.41 (10)°]. An intramolecular N-H⋯O hydrogen bond occurs. The fluoro-benzene ring is disordered over two positions [occupancy ratio = 0.59 (3):0.41 (3)]. Inter-molecular N-H⋯O and N-H⋯N hydroge...

The asymmetric unit of the title compound, C(5)H(2)Cl(2)N(2)O(2), consists of two crystallographically independent mol-ecules. The pyridine ring in each mol-ecule is essentially planar, with maximum deviations of 0.004 (4) and 0.007 (4) Å. Short Cl⋯O [3.09 (3) and 3.13 (4) Å] and Cl⋯Cl [3.38 (12) Å] contacts were observed. No significant inter-molecular inter-actions were observed in the crysta...

In the title compound, [Cd(C(2)N(3))(2)(C(6)H(6)N(2)O(3))(2)](n), the Cd(II) ion (site symmetry ) adopts a distorted trans-CdO(2)N(4) octa-hedral environment, being coordinated by two O-bonded 3-methyl-4-nitro-pyridine N-oxide ligands and four dicyanamide (dca) anions. The bridging dca anions lead to a polymeric chain propagating in [100].

The non-H atoms of the title compound, C(5)H(3)ClN(2)O(2), almost lie in a common plane (r.m.s. deviation = 0.090 Å). In the crystal, adjacent mol-ecules feature a short Cl⋯O contact [3.068 (4) Å], forming a chain; these chains are consolidated into a layer structure by non-classical C-H⋯O inter-actions.

The title mol-ecule, C(12)H(10)N(2)O(3), is twisted, the dihedral angle between the rings being 61.16 (13)°. The nitro group is approximately coplanar with the pyridine ring to which it is attached [O-N-C-C torsion angle = -178.1 (3)°]. Supra-molecular chains along [010] and mediated by C-H⋯O and π-π [centroid(pyrid-yl)-(benzene) distance = 3.8259 (18) Å] contacts feature in the crystal packing.
