The title compound, [Mn(C6H4N5)2(H2O)4]·4H2O, was obtained by the solution reaction of MnCl2 and 3-(2H-tetra­zol-5-yl)pyridine. The MnII atom, located on an inversion center, shows a slightly distorted octa­hedral geometry and is coordinated by two pyridine N atoms from two 5-(pyridin-3-yl)tetra­zolide ligands occupying trans positions and four water mol­ecules. In the crystal, the mononuclear complex mol­ecules and solvent water mol­ecules are connected into a three-dimensional framework by O—H⋯N and O—H⋯O hydrogen bonds.
