Abstract: In the title compound, [Mn(C₆H₄N₅O)₂(H₂O)₂]·2H₂O, the Mn^II ion is situated on an inversion centre and is coordinated by the O and N atoms of two bis-chelating 5-(2-pyridyl-1-oxide)tetrazolate ligands and two O atoms of two water molecules in a distorted octahedral geometry. All the water H atoms are involved in O-HN and O-HO hydrogen bonds with uncoordinated water O atoms and tetrazole N atoms, which link the molecules into a three-dimensional network.
