abstract: The title compound, C(22)H(30)N(2)O(2).H(2)O, is an 18-membered diaza-crown ether ligand containing two ether O and two aza N atoms. In the macrocyclic ring, the mean N.O distance is 4.526 (4) A. The macrocyclic inner-hole size, estimated as twice the mean distance of the donor atoms from their centroid, is approximately 2.29 A.
