title: Bis[4-(dimethyl-amino)-pyridinium] bis-[4-(dimethyl-amino)-pyridine-κN (1)]tetra-kis-(thio-cyanato-κN)manganate(II).
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 thio-cyanate anions and two N-bonded 4-(dimethyl-amino)-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 thio-cyanate anions and two 4-(dimethyl-amino)-pyridine ligands, as well as two protonated 4-(dimethyl-amino)-pyridinium cations. The discrete complex anions are connected to the non-coordinating pyridinium cations by weak N-H⋯S hydrogen-bonding inter-actions.
