Abstract

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.

Abstract

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]
