Bis[4-(dimethylamino)pyridinium] bis[4-(dimethylamino)pyridine-κN1]tetrakis(thiocyanato-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 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.
