1-[(6-Chloropyridin-3-yl)methyl]imidazolidin-2-iminium chloride
The title compound, C(9)H(12)ClN(4) (+)·Cl(-), is a natural metabolic product of imidacloprid [systematic name: (E)-1-(6-chloro-3-pyridyl-meth-yl)-N-nitro-imidazolidin-2-yl-idene-amine] and was obtained by the reduction of the latter using Fe in HCl. The dihedral angle between the pyridine and imidazole rings is 62.09 (12)°. The crystal structure is stabilized by N-H⋯Cl and C-H⋯Cl inter-actions...

In the cation of the title salt, C(11)H(12)IN(4) (+)·Cl(-), the two aromatic rings are oriented to each other at 9.3 (2)°. In the crystal, the two independent Cl(-) anions lie on twofold rotation axes. N-H⋯Cl hydrogen bonds between the cations and anions generate a supra-molecular layer parallel to (010).

In the cation of the title hydrated mol-ecular salt, C6H7N2O2 (+)·Cl(-)·H2O, the six-membered ring shows unequal bond lengths consistent with delocalization of electrons over two separate 6π systems with single bonds between them. In the crystal, the components are linked by N-H⋯Cl, N-H⋯O, O-H⋯Cl and O-H⋯O hydrogen bonds, generating double layers propagating in (100).
متن کاملGuanidinium chloride–18-crown-6 (2/1)
In the crystal of the title compound, 2CH(6)N(3) (+)·2Cl(-)·C(12)H(24)O(6), the 18-crown-6 mol-ecule is located across an inversion center. The guanidinium cation links to the 18-crown-6 mol-ecule and chloride anion via N-H⋯O and N-H⋯Cl hydrogen bonds.
متن کاملCrystal structures of 5-amino-N-phenyl-3H-1,2,4-dithiazol-3-iminium chloride and 5-amino-N-(4-chlorophenyl)-3H-1,2,4-dithiazol-3-iminium chloride monohydrate
The crystal and mol-ecular structures of the title salt, C8H8N3S2 (+)·Cl(-), (I), and salt hydrate, C8H7ClN3S2 (+)·Cl(-)·H2O, (II), are described. The heterocyclic ring in (I) is statistically planar and forms a dihedral angle of 9.05 (12)° with the pendant phenyl ring. The comparable angle in (II) is 15.60 (12)°, indicating a greater twist in this cation. An evaluation of the bond lengths in t...
