Packing diagram for hexaaquacobalt(II) bis­(4-carb­oxy­benzene­sulfonate) (CSD refcode ONOSUG; Wagner & Merzweiler, 2010BB46) viewed along [010] with dimeric hydrogen-bonded pillars. Layers of cations parallel to (001) are held together by hydrogen bonds involving the sulfonate groups. Direct and strong cation–cation hydrogen bonds are responsible for [100] chains with O⋯O distances of 2.86 Å and O—H⋯O angles of 175.0°. Adjacent neutral layers are further connected through hydrogen bonds involving the terminal carb­oxy­lic groups of the anions.
