In the title complex, [Zn2(C8H3NO6)2(CH4N2S)4]·2H2O, the carboxylate groups of the 3-nitrophthalate ligands coordinate in a bis-monodentate mode to the ZnII cations. This results in the formation of a centrosymmetric dimer containing two ZnII cations with distorted tetrahedral geometries provided by the O atoms of two different 3-nitrophthalate dianions and the S atoms of two non-equivalent coordinated thiourea molecules. The crystal structure exhibits N—H⋯O and O—H⋯O hydrogen bonds which link the dimers into a three-dimensional network.
