2-2,4,6-trinitrophenolato)barium(II)]Abstract: The asymmetric unit of the title compound, [Ba(C6H2N3O7)2(H2O)4]n, consists of a barium ion coordinated by two nitrophenolate ligands and four water molecules. Barium is decacoordinated by O atoms. These units are linked together through bridging nitro groups to form a one-dimensional polymeric chain. The three-dimensional packing is facilitated through hydrogen-bonding interactions mediated through water molecules. The coordination distances around Ba vary from 2.728 (4) to 3.138 (5) Å. The crystal sample, on exposure to air at room temperature for many days, slowly loses the water and peels out as filaments.
