To a suspension of 2,3,5,6-tetra-2-pyridylpyrazine (0.1945 g, 0.501 mmol) in acetone (20 ml) was added MnI2 (0.1575 g, 0.510 mmol) in acetone (30 ml) and refluxed for 5 h. The formed precipitate was separated by filtration, washed with acetone and dried at 50 °C, to give an orange powder (0.0779 g). Crystals suitable for X-ray analysis were obtained by slow evaporation from a 2-butanone solution.
Carbon-bound H atoms were positioned geometrically and allowed to ride on their respective parent atoms [C—H = 0.95 Å and Uiso(H) = 1.2Ueq(C)]. The H atoms of the water ligands and solvent molecule were located from Fourier difference maps then allowed to ride on their parent O atoms in the final cycles of refinement with O—H = 0.84 Å and Uiso(H) = 1.5 Ueq(O). The highest peak (1.06 e Å-3) and the deepest hole (-1.41 e Å-3) in the difference Fourier map are located 2.23 Å and 0.80 Å from the I2 atom, respectively. The Flack parameter is -0.01 (4) in the final cycles of refinement.
Mono- and dinuclear MnII complexes of 2,3,5,6-tetra-2-pyridylpyrazine (tppz; C24H16N6) ligand, such as [Mn(C2N3)(NO3)(tppz)(H2O)] (Callejo et al., 2009) and [Mn2Cl4(tppz)2] (Ha, 2011), have been investigated previously.
The asymmetric unit of the title compound, [MnI(tppz)(H2O)2]I.H2O, consists of a cationic MnII complex, an I- anion and a solvent water molecule (Fig. 1). In the complex, the MnII ion is six-coordinated in a considerably distorted octahedral environment defined by three N atoms of the tridentate tppz ligand, one I- anion and two O atoms of two water ligands. The main contribution to the distortion is the tight N—Mn—N chelating angles (Table 1), which results in non-linear trans arrangement of the N3—Mn1—N6 bond [N3—Mn1—N6 = 143.1 (3)°]. The apical O1—Mn1—O2 and I1—Mn1—N1 bond angles are 167.0 (2)° and 173.04 (19)°, respectively. The three Mn—N(pyrazine or pyridyl) bond lengths are roughly equivalent and slightly longer than the Mn—O(H2O) bonds (Table 1). In the crystal structure, the pyrazine and pyridyl rings are nearly planar [maximum deviation = 0.020 (6) Å for pyrazine and 0.034 (6) Å for pyridyl]. The dihedral angles between the pyridyl rings and their carrier pyrazine ring are 26.5 (2)° and 27.0 (2)° for the coordinated pyridyl rings, and 51.3 (3)° and 43.2 (2)° for the uncoordinated pyridyl rings, respectively. The complex, anion and solvent water molecule are linked by intermolecular O—H···O, O—H···N and O—H···I hydrogen bonds (Fig. 2, Table 2). In addition, the complex displays numerous inter- and intramolecular π-π interactions between adjacent six-membered rings, the shortest ring centroid-centroid distance being 4.032 (5) Å.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

Mono- and dinuclear MnII complexes of 2,3,5,6-tetra-2-pyridylpyrazine (tppz; C24H16N6) ligand, such as [Mn(C2N3)(NO3)(tppz)(H2O)] (Callejo et al., 2009) and [Mn2Cl4(tppz)2] (Ha, 2011), have been investigated previously.
The asymmetric unit of the title compound, [MnI(tppz)(H2O)2]I.H2O, consists of a cationic MnII complex, an I- anion and a solvent water molecule (Fig. 1). In the complex, the MnII ion is six-coordinated in a considerably distorted octahedral environment defined by three N atoms of the tridentate tppz ligand, one I- anion and two O atoms of two water ligands. The main contribution to the distortion is the tight N—Mn—N chelating angles (Table 1), which results in non-linear trans arrangement of the N3—Mn1—N6 bond [N3—Mn1—N6 = 143.1 (3)°]. The apical O1—Mn1—O2 and I1—Mn1—N1 bond angles are 167.0 (2)° and 173.04 (19)°, respectively. The three Mn—N(pyrazine or pyridyl) bond lengths are roughly equivalent and slightly longer than the Mn—O(H2O) bonds (Table 1). In the crystal structure, the pyrazine and pyridyl rings are nearly planar [maximum deviation = 0.020 (6) Å for pyrazine and 0.034 (6) Å for pyridyl]. The dihedral angles between the pyridyl rings and their carrier pyrazine ring are 26.5 (2)° and 27.0 (2)° for the coordinated pyridyl rings, and 51.3 (3)° and 43.2 (2)° for the uncoordinated pyridyl rings, respectively. The complex, anion and solvent water molecule are linked by intermolecular O—H···O, O—H···N and O—H···I hydrogen bonds (Fig. 2, Table 2). In addition, the complex displays numerous inter- and intramolecular π-π interactions between adjacent six-membered rings, the shortest ring centroid-centroid distance being 4.032 (5) Å.
