The asymmetric unit of the title compound, [MnI(C(10)H(9)N(3))(2)(H(2)O)]I, contains a cationic Mn(II) complex and an I(-) anion. In the complex, the Mn(II) ion is six-coordinated in a considerably distorted cis-N(4)IO octa-hedral environment defined by four N atoms of the two chelating di-2-pyridyl-amine (dpa) ligands, one I(-) anion and one O atom of a water ligand. As a result of the different trans effects of the I, N and O atoms, the Mn-N bond trans to the I atom is slightly longer than the Mn-N bond trans to the N or O atoms. The dpa ligands are not planar, with dihedral angles between the two pyridine rings of 26.2 (4) and 26.5 (4)°. The complex cations are stacked in columns along the a axis and are linked to the anions by inter-molecular O-H⋯I and N-H⋯I hydrogen bonds.
标题化合物[MnI(C₁₀H₉N₃)₂(H₂O)]I的不对称单元包含一个阳离子Mn(II)配合物和一个I⁻阴离子。在该配合物中，Mn(II)离子在由两个螯合的二-2-吡啶胺（dpa）配体的四个N原子、一个I⁻阴离子和一个水配体的O原子所定义的严重扭曲的顺式-N₄IO八面体环境中呈六配位。由于I、N和O原子的不同反位效应，与I原子反位的Mn-N键略长于与N或O原子反位的Mn-N键。dpa配体不是平面的，两个吡啶环之间的二面角为26.2 (4)°和26.5 (4)°。配合物阳离子沿a轴堆积成列，并通过分子间的O-H⋯I和N-H⋯I氢键与阴离子相连。
