Hexaaqua-cadmium(II) dipicrate monohydrate.

In the structure of the title compound, [Cd(H(2)O)(6)](C(6)H(2)N(3)O(7))(2)·H(2)O, the Cd(II) ion is located on an inversion center and is coordinated by six water mol-ecules in an octa-hedral geometry. The picrate anions have no coordination inter-actions with the Cd(II) ion. The three nitro groups are twisted away from the attached benzene ring, making dihedral angles of 17.89 (3), 27.94 (4) and 13.65 (3)°. There are numerous O-H⋯O hydrogen bonds in the crystal structure, involving coordinated and uncoordinated water molecules.
