The crystal belongs to triclinic, space group Pī with a = 7.8364 (16), b = 8.3607 (13), c = 9.4762 , α = 61.900 (12), β = 78.970 (16), γ = 80.008 (16) °, V = 535.06 (16) ~ 3, Z = 1 and calc = 1.277g / cm ~ 3. (000) = 226. The macrocylic tetraamine cation contains two protonated secondary amine N atoms and two secondary amine N atoms. The water molecules are distinguished by their inequality in structure formation. They are involved in different types of intermolecular hydrogen bonding in the crystal lattice .
