چکیده
The title salt, C20H26N3O2(+)·Cl(-), lies across a twofold crystallographic axis with the central N atom of the cation and the chloride anion sitting on this axis, Z' = 0.5. There is an intra-molecular hydrogen bond between the hy-droxy H atom and the imino N atom. The chloride anion and the cation are connected into chains along the a axis by an N-H⋯Cl hydrogen bond. In the crystal, the chains are linked via C-H⋯Cl interactions forming two-dimensional networks lying parallel to (101).

The title compounds, C23H21ClN2O2, differ from each other only by the position of the Cl atom on the corresponding benzene ring: meta relative to the central sp3 C atom for (I) and para for (II). In (I), the hy-droxy-phenyl rings are almost parallel, the dihedral angle between the mean planes being 9.2 (2)°, but in (II), the relative position of the ring is different, characterized by a dihedra...

In the title compound, C(6)H(19)N(4) (+)·Cl(-)·CH(2)Cl(2), the non-H atoms of the ammonium ion show non-crystallographic C(3) symmetry. The chloride ion is embedded in a framework of seven crystallographically independent hydrogen bonds (five N-H⋯Cl and two C-H⋯Cl), which form layers parallel to the (100) plane. Two N---H...N bonds also occur.

In the title hydrated salt, 2C(3)H(11)N(2) (+)·C(10)H(6)O(6)S(2) (2-)·2H(2)O, the anion lies on a center of inversion; its sulfonate -SO(3) group features one S-O bond that is longer than the other two. The O atom of this longer bond is the hydrogen-bond acceptor to the amino H atom of one cation and the ammonium H atom of another cation. In the crystal, N-H⋯O and O-H⋯O hydrogen bonds link the ...

In the title compound, C(29)H(25)N(3)O(3), the imine double bond has an E configuration. The dihedral angle between the hy-droxy-phenyl and benzene rings in the imine moiety is 26.95 (9)°, and the dihedral angle between the hy-droxy-phenyl and benzimidazole rings in the other moiety is 14.83 (9)°. These angles are probably limited to small values as a consequence of two strong intra-molecular O...
