%X In the title compound, (C6H5N5)2[Mg(H2O)6]Cl2, the asymmetric unit contains one zwitterionic 5-(pyridinium-3-yl)tetrazol-1-ide molecule, one half of an [Mg(H2O)6]2+ cation (overline{1} symmetry) and one chloride ion. The MgII ion is surrounded by six water molecules, with their O atoms located at the apices, exhibiting a slightly distorted octahedral coordination. Mg¡ªO bond lengths range from 2.0526 (14) to 2.0965 (16)   [mean value = 2.068  ]. The pyridine and tetrazole rings are nearly coplanar and only twisted from each other by a dihedral angle of 5.68 (1)¡ã. The zwitterionic organic molecules, anions and cations are connected by O¡ªH...Cl, O¡ªH...N and N¡ªH...Cl hydrogen bonds, leading to the formation of a three-dimensional network.
