In the title compound, [Pt2(C6H4NO 3)2(NH3)4]2(NO 3)4·4H2O, a head-to-head dimer has an association with another dimer unit through an inversion center to give a tetraplatinum chain structure. The interaction is stabilized not only by a metal-metal interaction but also by four hydrogen bonds formed between the ammines and the O atoms of bridging amidates [N⋯O = 2.988(17) and 3.030 (16) Å]. The intra- and interdimer Pt-Pt distances within the tetranuclear cation are 2.9023 (8) and 3.1821 (11) Å, respectively.
