The crystal structures of the title salts, (CHN)[Mn(NCS)] () and (CHN)[Mn(NCS)] (), consist of manganese(II) cations that are tetra-hedrally () or trigonal-bipyramidally () coordinated to four or five terminal N-bonded thio-cyanate ligands, respectively, into discrete anionic complexes. The negative charge is compensated by two () or three () 4-(di-methyl-amino)-pyridinium cations, which are protonated at the pyridine N atom. The asymmetric unit of compound consists of one anionic complex and two 4-(di-methyl-amino)-pyridinium cations, whereas that of compound consists of two anionic complexes and six 4-(di-methyl-amino)-pyridinium cations, all of them located in general positions. These complexes are linked by N-H⋯S, C-H⋯S and C-H⋯N hydrogen-bonding inter-actions between the 4-(di-methyl-amino)-pyridinium cations and the thio-cyanate ligands into three-dimensional network structures.
标题盐（CHN）[Mn（NCS）]（）和（CHN）[Mn（NCS）]（）的晶体结构由锰（II）阳离子组成，这些阳离子分别以四面体（）或三角双锥（）方式与四个或五个末端N键合的硫氰酸酯配体配位，形成离散的阴离子配合物。负电荷由两个（）或三个（）4-（二甲基氨基）吡啶鎓阳离子补偿，这些阳离子在吡啶N原子处质子化。化合物的不对称单元由一个阴离子配合物和两个4-（二甲基氨基）吡啶鎓阳离子组成，而化合物的不对称单元由两个阴离子配合物和六个4-（二甲基氨基）吡啶鎓阳离子组成，它们都位于一般位置。这些配合物通过4-（二甲基氨基）吡啶鎓阳离子与硫氰酸酯配体之间的N-H⋯S、C-H⋯S和C-H⋯N氢键相互作用连接成三维网络结构。
