title: Bis{6-[4-(2-ethyoxyphenyl-diazen-yl)phen-oxy]hexa-nol} monohydrate.
abstract: The asymmetric unit of the title compound, 2C(20)H(26)N(2)O(3)·H(2)O, contains two independent mol-ecules and one water mol-ecule. The azo bonds adopt trans conformations and the dihedral angles between the aromatic rings in the two organic mol-ecules are 4.5 (2) and 1.5 (2)°. In the crystal structure, O-H⋯O and C-H⋯O hydrogen bonds help to establish the packing.
