In the crystal structure of the title compound, [Mn(C(3)H(4)N(2))(6)]Mn(C(3)H(4)N(2))(3)(H(2)O)(3)(2), there are uncoordinated naphthalene-dicarboxyl-ate dianions and two kinds of Mn(II) complex cations, both assuming a distorted octa-hedral geometry. One Mn(II) cation is located on an inversion center and is coordinated by six imidazole mol-ecules, while the other Mn(II) cation is located on a twofold rotation axis and is coordinated by three water mol-ecules and three imidazole units. The naphthalene-dicarboxyl-ate dianions are linked to both Mn(II) complex cations via O-H⋯O and N-H⋯O hydrogen bonding, but no π-π stacking is observed between aromatic rings in the crystal structure.
在标题化合物[Mn(C₃H₄N₂)₆]Mn(C₃H₄N₂)₃(H₂O)₃₂的晶体结构中，存在未配位的萘二甲酸根二价阴离子和两种Mn(II)络合阳离子，二者均呈扭曲的八面体几何构型。一个Mn(II)阳离子位于对称中心，由六个咪唑分子配位，而另一个Mn(II)阳离子位于二重旋转轴上，由三个水分子和三个咪唑单元配位。萘二甲酸根二价阴离子通过O—H⋯O和N—H⋯O氢键与两种Mn(II)络合阳离子相连，但在晶体结构中芳环之间未观察到π-π堆积。
