Özet
The title compound, C22H26N2O3, is a 19-membered Schiff base crown ether ligand containing two imine-N and three etheral-O atoms. In the macrocyclic ring, the mean N. . .O distance is 6.248 (3) Å. The relative macrocyclic inner hole size, estimated as twice the mean distance of the donor atoms from their centroid is approximately 2.53 Å. The mean C=N imine bond length [1.256 (3) Å] and C-N=C imine bond angle [117.8 (2)°] are smaller than the corresponding values in salicylaldimine and naphthaldimine Schiff base ligands.
