Single crystals of the title organic-inorganic hybrid, {(C(5)H(7)N(2))(2)[MnCl(2)(H(2)O)(2)]Cl(2)}(n), were synthesized from an ethanol solution containing manganese(II) chloride tetra-hydrate and 4-amino-pyridine under acidic conditions. The asymmetric unit contains a disordered organic cation (occupancies in the ratio 0.72:0.28), a chloride anion and an MnCl(H(2)O) moiety with the Mn(II) atom located on an inversion center. The structure is built up of infinite chains of edge-sharing [MnCl(4)(H(2)O)(2)] octa-hedra developing parallel to the a axis which are separated by the 4-amino-pyridinium ions and discrete chloride ions. The organic cations occupy the empty space around each inorganic chain. Structural cohesion is organized through N-H⋯Cl and O-H⋯Cl hydrogen bonds, which build up a three-dimensional network.
标题有机-无机杂化物{(C₅H₇N₂)₂[MnCl₂(H₂O)₂]Cl₂}ₙ的单晶是在酸性条件下，由含有四水合氯化锰和4-氨基吡啶的乙醇溶液合成的。不对称单元包含一个无序的有机阳离子（占有率比例为0.72:0.28）、一个氯离子和一个MnCl(H₂O)部分，其中Mn(II)原子位于一个反演中心上。该结构由平行于a轴延伸的、通过共用边连接的[MnCl₄(H₂O)₂]八面体的无限链构成，这些链被4-氨基吡啶鎓离子和离散的氯离子隔开。有机阳离子占据每条无机链周围的空隙。结构凝聚力通过N-H⋯Cl和O-H⋯Cl氢键组织起来，形成一个三维网络。
