Diaqua-bis-[5-(1-oxidopyridin-1-ium-2-yl)-1,2,3,4-tetrazolido]manganese(II) di-hydrate

Abstract

In the title compound, [Mn(C(6)H(4)N(5)O)(2)(H(2)O)(2)]·2H(2)O, 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)tetra-zolate ligands and two O atoms of two water mol-ecules in a distorted octa-hedral geometry. All the water H atoms are involved in O-H⋯N and O-H⋯O hydrogen bonds with uncoordinated water O atoms and tetra-zole N atoms, which link the mol-ecules into a three-dimensional network.
