In the title compound, [Fe(C(24)H(16)N(6))(2)][N(CN)(2)](2)·4.5H(2)O, 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.
