In the structure of the title salt, 2C(12)H(10)N(3)O(4) (+)·C(12)H(8)O(6)S(2) (2-)·3H(2)O, determined at 173 K, the biphenyl-4,4'-disulfonate dianions lie across crystallographic inversion centres with the sulfonate groups inter-acting head-to-head through centrosymmetric cyclic bis-(water)-bridged hydrogen-bonding associations [graph set R(4) (4)(11)], forming chains. The 2-(2,4-dinitro-benz-yl)pyridinium cations are linked to these chains through pyridinium-water N-H⋯O hydrogen bonds and a two ...[more]
