The 8H6N4)2(H2O)]I·2H2O, contains a cationic MnII complex, an I− anion and two solvent water molecules. In the complex, the MnII ion is six-coordinated in a considerably distorted octahedral environment defined by four N atoms of the two chelating 2,2′-bipyrimidine (bpym) ligands, one I− anion and one O atom of a water ligand. As a result of the different trans effects of the I and O atoms, the Mn—N bond trans to the I atom is slightly longer than the Mn—N bond trans to the O atom. The dihedral angle between the least-squares planes of the two bpym ligands [maximum deviation = 0.088 (4) Å] is 76.48 (6)°. In the crystal, the complex cation, the anion and the solvent water molecules are linked by intermolecular O—H⋯O, O—H⋯I and O—H⋯N hydrogen bonds.

To a solution of 2,2'-bipyrimidine (0.1587 g, 1.003 mmol) in acetone (40 ml) was added MnI2 (0.1540 g, 0.499 mmol) and refluxed for 3 h. The formed precipitate was separated by filtration, washed with acetone and dried at 50 °C, to give a yellow powder (0.0701 g). Crystals suitable for X-ray analysis were obtained by slow evaporation from a methanol 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 ligand and solvent molecules were located from Fourier difference maps then allowed to ride on their parent O atoms in the final cycles of
with O—H = 0.84 Å and Uiso(H) = 1.5 Ueq(O). The highest peak (0.97 e Å-3) and the deepest hole (-1.15 e Å-3) in the difference Fourier map are located 1.38 Å and 0.85 Å from the I1 atom, respectively.Mononuclear MnII complexes of 2,2'-bipyrimidine (bpym, C8H6N4) ligand, such as [Mn(bpym)2(H2O)2](ClO4)2.2H2O (Hong et al., 1996), [Mn(bpym)2(H2O)2](BF4)2.2H2O (Smith et al., 2001) and [MnBr2(bpym)2].CH3CN (Ha, 2011), have been investigated previously.

of the title compound, [MnI(bpym)2(H2O)]I.2H2O, contains a cationic MnII complex, an I- anion and two solvate water molecules (Fig. 1). In the complex, the MnII ion is six-coordinated in a considerably distorted octahedral environment defined by four N atoms of the two chelating bpym ligands, one I- anion and one O atom of a water ligand in a cis-N4IO coordination geometry. The main contribution to the distortion of the ocataheron is the tight N—Mn—N chelating angles (Table 1), which results in non-linear trans axes [<O1—Mn1—N1 = 167.23 (13)°, <I1—Mn1—N8 = 172.44 (9)° and <N4—Mn1—N5 = 158.58 (13)°]. The Mn—N(bpym) bond lengths are slightly different and longer than the Mn—O(H2O) bond (Table 1). Because of the different trans effects of the I and O atoms, the Mn1—N8 bond trans to the I atom is somewhat longer than the Mn1—N1 bond trans to the O atom. The dihedral angle between the least-squares planes of the two bpym ligands [maximum deviation = 0.088 (4) Å] is 76.48 (6)°. In the the complex, anion and solvate water molecules are linked by intermolecular O—H···O, O—H···I and O—H···N hydrogen bonds (Fig. 2, Table 2). In addition, the complexes display numerous inter- and intramolecularFor the crystal structures of mononuclear 2,2'-bipyrimidine MnII complexes, see: Hong et al. (1996); Smith et al.

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. |

Mononuclear MnII complexes of 2,2'-bipyrimidine (bpym, C8H6N4) ligand, such as [Mn(bpym)2(H2O)2](ClO4)2.2H2O (Hong et al., 1996), [Mn(bpym)2(H2O)2](BF4)2.2H2O (Smith et al., 2001) and [MnBr2(bpym)2].CH3CN (Ha, 2011), have been investigated previously.
The asymmetric unit of the title compound, [MnI(bpym)2(H2O)]I.2H2O, contains a cationic MnII complex, an I- anion and two solvate water molecules (Fig. 1). In the complex, the MnII ion is six-coordinated in a considerably distorted octahedral environment defined by four N atoms of the two chelating bpym ligands, one I- anion and one O atom of a water ligand in a cis-N4IO coordination geometry. The main contribution to the distortion of the ocataheron is the tight N—Mn—N chelating angles (Table 1), which results in non-linear trans axes [<O1—Mn1—N1 = 167.23 (13)°, <I1—Mn1—N8 = 172.44 (9)° and <N4—Mn1—N5 = 158.58 (13)°]. The Mn—N(bpym) bond lengths are slightly different and longer than the Mn—O(H2O) bond (Table 1). Because of the different trans effects of the I and O atoms, the Mn1—N8 bond trans to the I atom is somewhat longer than the Mn1—N1 bond trans to the O atom. The dihedral angle between the least-squares planes of the two bpym ligands [maximum deviation = 0.088 (4) Å] is 76.48 (6)°. In the crystal structure, the complex, anion and solvate water molecules are linked by intermolecular O—H···O, O—H···I and O—H···N hydrogen bonds (Fig. 2, Table 2). In addition, the complexes display numerous inter- and intramolecular π-π interactions between adjacent pyrimidine rings, the shortest ring centroid-centroid distance being 3.611 (2) Å.
