| Abstract: | In the crystal structure of the title compound, [Fe(H2O)6](C6H2N3O7)2·2H2O, the centrosymmetric cationic iron complexes and picrate anions form separate stacks extending along the b axis. No picrate species ligate to the metal cation. Picrate ions are linked to one another in the stack via short intermolecular C⃛C contacts of 3.083 (4) and 3.055 (4) Å. Variable‐temperature X‐ray diffraction measurements performed between room temperature and 93 K showed a linear decrease of the lattice parameters, suggesting that there is no phase transition. |
