The title solvated salt, C 21 H 17 N 7   2+ ·SO 4   2− ·CH 3 OH, was obtained when we attempted to prepare the complex of ferrous sulfate and 2,6-bis­[3-(pyridin-2-yl)-1 H -pyrazol-1-yl]pyridine in methanol. The dihedral angles between adjacent pyridine and pyrazole rings range from 3.8 (1) to 13.4 (1)°. An intra­molecular N—H⋯N hydrogen bond occurs. In the crystal, N—H⋯O and O—H⋯N hydrogen bonds between solvent methanol mol­ecules and the cations generate zigzag chains along [110].
