The title solvated salt, C21H17N7 (2+)·SO4 (2-)·CH3OH, was obtained when we attempted to prepare the complex of ferrous sulfate and 2,6-bis-[3-(pyridin-2-yl)-1H-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 intra-molecular N-H⋯N hydrogen bond occurs. In the crystal, N-H⋯O and O-H⋯N hydrogen bonds between s...
