Abstract

In the title compound, [Fe(C₂₄H₁₆N₆) ₂][N(CN)₂]₂·4.5H₂O, the central iron(II) ion is hexa-coordinated by six N atoms of two tridentate 2,3,5,6-tetra-2-pyridylpyrazine (tppz) ligands. Two dicyanamide anions [dca or N(CN)₂ ^-] act as counter-ions, and 4.5 water mol-ecules act as solvation agents. The structure contains isolated cationic iron(II)-tppz complexes and the final neutrality is obtained with the two dicyanamide anions. One of the dicyanamide anions and a water mol-ecule are disordered with an occupancy ratio of 0.614 (8):0.386 (8). O - H⋯O, O - H⋯N and C - H⋯O hydrogen bonds involving dca, water and tppz mol-ecules are observed.
