Abstract

The title molecule, C21H24N2O2, is a macrocyclic multidentate Schiff base ligand containing two imine N and two ether O atoms which has a crystallographic twofold axis. The macrocyclic inner-hole size, estimated as twice the mean distance of the donor atoms from their centroid, is approximately 2.08 Angstrom.
