Abstract: The Co atom in the title compound, [Co(C₁₀H₁₄N₄)₂(H₂O)₂](NO₃)₂, is six-coordinate in a trans-N₄O₂ octahedral geometry as a consequence of bridging by the bipyrazole ligand; the bridging leads to the formation of a polycationic layer. The layers interact with the anions through hydrogen bonds, generating a three-dimensional hydrogen-bonded network. The structure is porous as 33.4% of its unit-cell volume is empty space. The Co atom lies on a special position of site symmetry 222, the bipyrazole ligand lies on a special position of site symmetry 2, the water molecule on another special position of site symmetry 2, and the nitrate anion on a special position of site symmetry m.
