Single crystals of bis(1,2-diaminepropane) di-μ-chloro-bis[diaquadichloromanganate(II)] dichloride have been prepared by evaporation from ethanoic solution. The triclinic X-ray crystal structure is built as layers of centrosymmetric dimers of [Mn(Cl)₄(H₂O)₂]²⁻ octahedra and 1,2-diaminopropane. The inorganic part consists of Mn octahedra sharing one edge and distributed in the basal ac plane along the a direction. These doubly negative charged layers are separated along the b axis by a positively charged diamine propane layer. One Cl⁻ anion contributes to the electroneutrality of the crystal interacting with both inorganic – through a hydrogen bond network to the two water molecules coordinated to Mn – and organic layers via the NH₃⁺ ammonium group. Differential scanning calorimetry shows two endothermic main peaks at T = 366 K and T = 375 K related to the release of the water molecules. The resulting dehydrated material is C-centered monoclinic as shown by powder X-ray diffraction.

新型杂化钙钛矿：双(1,2-二氨基丙烷)二-μ-氯-双[二氯二氯锰酸(II)]二氯化物的合成、晶体结构和相变

通过从乙醇溶液中蒸发制备了双(1,2-二胺丙烷)二-μ-氯-双[四二氯锰酸(II)]二氯化物的单晶。_{三斜X射线晶体结构由[Mn(Cl) 4} (H ₂ O) ₂ ] ²⁻八面体和1,2-二氨基丙烷的中心对称二聚体层构成。无机部分由共享一条边的Mn八面体组成，并沿a方向分布在ac基面中。这些带双负电荷的层沿b轴被带正电荷的二胺丙烷层分隔开。一个 Cl ^-阴离子有助于晶体与无机层（通过与 Mn 配位的两个水分子的氢键网络）和有机层（通过 NH ₃ ⁺铵基团）相互作用的电中性。差示扫描量热法显示在T = 366 K 和T = 375 K处有两个吸热主峰，与水分子的释放有关。如粉末X射线衍射所示，所得脱水材料是C中心单斜晶系。
