Abstract: The title compound, [Zn(H2O)6][H3NC10H5(SO3)2]2·4H2O (Zn site symmetry ), is isostructural with its nickel(II) and cobalt(II) analogues. An extensive network of N-HO and O-HO hydrogen bonds involving the ammonio group, water molecules, and sulfonate O atoms helps to establish the packing. One of the uncoordinated water molecules is disordered over at least two sites (modelled over two positions with site occupancy ratio ca 2:1).
