Abstract: In the crystal structure of the title compound, (C7H11N2)2[Mn(NCS)4(C7H10N2)2], the manganese(II) cations are coordinated by four N-bonded thiocyanate anions and two N-bonded 4-(dimethylamino)pyridine ligands into discrete complex dianions. For charge balance, two 4-(dimethylamino)pyridine counter cations are present, which do not coordinate to the metal cation. The asymmetric unit consists of one manganese(II) cation, four thiocyanate anions and two 4-(dimethylamino)pyridine ligands, as well as two protonated 4-(dimethylamino)pyridinium cations. The discrete complex anions are connected to the non-coordinating pyridinium cations by weak N-H...S hydrogen-bonding interactions.
