Abstract: In the title compound, [Mg(H2O)6]Br2·2C6H5N5, the MgII 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)°. The zwitterions, Br anions and complex cations are connected by O-HBr, O-HN and N-HBr hydrogen bonds, leading to the formation of a three-dimensional network.
