In the title compound, [Mn(C12H8N2)2(H2O)2]SO4·6H2O, the complex cations assemble into positively charged sheets parallel to (010) via intermolecular - stacking interactions with a mean interplanar distance of 3.410 (6) along  and 3.465 (5) Å along . The sulfate anions and uncoordinated water molecules are interconnected between these layers by hydrogen bonds, forming negatively charged layers which are linked to the positive layers through O-HO hydrogen bonds, forming a three-dimensional architecture. Both the positive and negative sheets are stacked along  in an ABAB sequence, the A layers being shifted by 1/2a along  with respect to the B layers. One of the uncoordinated water molecules is equally disordered over two positions.
