N,N′-[(1,7-Dioxa-4,10-diazacyclododecane-2,10-diyl)diethylene]diphthalimide

Abstract

The title compound, C28H32N4O6, crystallizes with one half-mol­ecule in the asymmetric unit and the other half generated by an inversion centre. The compound has a crown structure and is an important inter­mediate for the synthesis of biologically active 1,7-dioxa-4,10-diaza­cyclo­dodecane derivatives. Inter­molecular π–π stacking inter­actions, with a perpendicular distance of 3.57 Å, involving the planar phthalimide groups and weak C—H⋯O hydrogen bonds are present.
