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.
