Özet

The title compound, C20H26N2O3.0.5H(2)O, contains a 17-membered diaza-crown ether ligand with three ether O and two N atoms. It consists of the macrocyclic ligand and one half water molecule; the latter possesses crystallographically imposed C-2 symmetry. In the macrocyclic ring, the mean N...O distance is 3.995 (4) Angstrom. The macrocyclic inner hole size, estimated as twice the mean distance of the donor atoms from their centroid, is approximately 1.29 Angstrom.
