The organically templated compound (NH4)(3)(4,4'-Hbpy)[((VO)-O-IV)(6)(mu(4)-O)(2)(mu(3)-OH)(2)(mu-SO3)(4)(mu-SO3)]center dot 15/2 H2O 1 is the first example of an extended structure in which a polyoxometalate anion, [(H2V6S4O22)-S-IV-O-IV](2-), is linked by the pyramidal mu(2)-bridging sulfite group forming a linear polymeric {V-6}(eta) chain. Two such chains are linked into a 'double-rung ladder' assembly via two different hydrogen bonds provided by 4,4'-Hbpy(+) cations.
