The title compound, C17H16Cl2N2, adopts a `vault' conformation. The mol­ecules are linked by a pair of C—H⋯N hydrogen bonds into a centrosymmetric dimer with an R22(18) ring. These dimers are linked by a weak centrosymmetric π–π inter­action into a chain along the [001] direction, and these chains are connected by van der Waals inter­actions, resulting in a three-dimensional network structure.

The title compound, C50H68N6O8, is a new Schiff base compound synthesized by the condensation reaction of paeonol and N, N, N′, N′-tetra­kis(3-amino­prop­yl)ethyl­ene­diamine in absolute methanol. The mol­ecule possesses a crystallographically imposed centre of symmetry and demonstrates normal values of bond lengths and angles. [ABSTRACT FROM AUTHOR]

In the title compound, C19H18N2O4, the methyl group is disordered. The mol­ecule is centrosymmetric and has a trans configuration ( E, E). [ABSTRACT FROM AUTHOR]

The title complex, [ZnCl2(C16H17NO2)2], displays a distorted tetra­hedral coordination geometry around the ZnII ion. The Schiff base inner salt, (benzyl­imino)ethyl-5-methoxy­phenol, coordinates in a monodentate manner to the ZnII ion via the deprotonated hydr­oxy groups. The protonated imino groups form intra­molecular hydrogen bonds with the deprotonated hydroxyl groups of the same Schiff base ligand. [ABSTRACT FROM AUTHOR]
