چکیده
In the title salt hydrate, C(22)H(30)N(2)O(6) (2+)·2Cl(-)·CH(4)O, the dication adopts a U-shaped conformation whereby the benzene rings are splayed out from the chain linking them. All components of the asymmetric unit are linked into a cohesive entity by a combination of O-H⋯Cl(-), N(+)-H⋯Cl(-) and N(+)-H⋯O charge-assisted hydrogen-bonding inter-actions. The assemblies thus formed are linked into supra-molecular helical chains along [010] via C-H⋯O contacts. The resulting chains are, in turn, consolidated into the three-dimensional crystal structure by C-H⋯π contacts.

The title compound, C(28)H(28)N(2)O(4), crystallizes in a zwitterionic form with deprotonated naphthol hy-droxy groups and protonated imine N atoms. The asymmetric unit contains one half-mol-ecule located on a twofold rotation axis. Intra-molecular N-H⋯O hydrogen bonds occur and the two bicyclic ring systems form a dihedral angle of 64.2 (1)°. In the crystal, weak inter-molecular C-H⋯O hydrogen...
