In the title compound, C(23)H(26)Cl(2)N(4)O(4),the dihedral angle between the mean planes of the pyridine and 3-chloro-phenyl rings is 22.63 (2)°. The nitro group is in a Z conformation.

In the title compound, C(21)H(21)ClN(6)O(2)·C(2)H(6)O, a member of the insecticidal active neonicotinoid group of compounds, the 1,4-dihydro-pyridine ring adopts a boat conformation. An intra-molecular C-H⋯O hydrogen bond occurs while the components are linked by an N-H⋯O interaction. The crystal packing is stablized by O-H⋯N hydrogen bonds and C-H⋯O interactions.

In the title compound, C(20)H(20)ClFN(4)O(3), the tetra-hydro-pyridone ring adopts a skew boat conformation. The dihedral angle between the mean planes of the benzene and pyridine rings is 80.7 (3)°. In the crystal, weak C-H⋯O inter-actions are observed.

In the title compound, C(15)H(13)N(3)O(4), the two substituted benzene rings form a dihedral angle of 10.9 (3)°. In the crystal, inter-molecular C-H⋯O and N-H⋯O hydrogen bonds link mol-ecules into chains running parallel to [101].

In the title compound, C(15)H(13)N(3)O(4), the two substituted benzene rings form a dihedral angle of 5.0 (3)°. In the crystal, inter-molecular N-H⋯O hydrogen bonds link mol-ecules into chains along the b axis.

In the title compound C(13)H(19)N(5)O(4), which belongs to the insecticidally active neonicotinoid group of compounds, the triazane ring exhibits a half-chair conformation. The large discrepancy between the two nitro O-N-N bond angles [116.1 (2) and 123.98 (19)°] may be attributed to intra-molecular N-H⋯O hydrogen bonding involving one of the nitro O atoms as the acceptor. The delocalization of the electrons extends as far as the nitro group, forming coplanar π-electron networks. In the crystal, inversion dimers lined by pairs of N-H⋯O hydrogen bonds occur.

In the title compound, C(11)H(15)ClN(6)O(4)S, which belongs to the neonicotinoid class of insecticidally active heterocyclic compounds, the six-membered triazine ring adopts an opened envolope conformation. The planar nitro imine group [dihedral angle between nitro and imine groups = 1.07 (7)°] and the thia-zole ring are oriented at a dihedral angle of 69.62 (8)°. A classical intra-molecular N-H⋯O hydrogen bond is found in the mol-ecular structure. Moreover, one classical inter-molecular N-H⋯N and four non-classical C-H⋯O and C-H⋯N hydrogen bonds are also present in the crystal structure. Besides inter-molecular hydrogen bonds, the Cl atom forms an inter-molecular short contact [3.020 (2) Å] with one of the nitro O atoms.
