Hexaaquamagnesium dibromide 5-(pyridinium-3-yl)tetrazol-1-ide

In the title compound, [Mg(H(2)O)(6)]Br(2)center dot 2C(6)H(5)N(5), the Mg(II) atom, lying on an inversion center, is coordinated by six water molecules in a distorted octahedral geometry. The pyridine and tetrazole rings in the 5-(pyridinium-3-yl) tetrazol-1-ide zwitterion are nearly coplanar, twisted from each other by a dihedral angle of 5.70 (1)degrees. The zwitterions, Br anions and complex cations are connected by O-H center dot center dot center dot Br, O-H center dot center dot center dot N and N-H center dot center dot center dot Br hydrogen bonds, leading to the formation of a three-dimensional network.
