The 8H6N4)2(H2O)2](ClO4)2·2CH3NO2·H2O, contains one half of a cationic MnII complex, a ClO4− anion, a nitromethane solvent molecule and one half-molecule of water. The complex molecule and the solvent water molecule are located on a twofold rotation axis. In the complex, the MnII ion has a distorted cis-N4O2 octahedral coordination geometry defined by four N atoms of the two chelating 2,2′-bipyrimidine ligands and two O atoms of water molecules. In the crystal, the complex cations, anions and solvent molecules are linked by intermolecular O—H⋯N, O—H⋯O and weak C—H⋯O hydrogen bonds. The ClO4− anion is disordered over two sites with a site-occupancy factor of 0.512 (12) for the major component.

To a solution of Mn(ClO4)2.6H2O (0.3617 g, 0.999 mmol) in EtOH (20 ml) was added 2,2'-bipyrimidine (0.1586 g, 1.003 mmol) and stirred for 3 h at room temperature. The formed precipitate was separated by filtration, washed with EtOH and dried at 50°C, to give a pale yellow powder (0.2713 g). Crystals suitable for X-ray analysis were obtained by slow evaporation from a CH3NO2 solution.
Carbon-bound H atoms were positioned geometrically and allowed to ride on their respective parent atoms [C—H = 0.95 Å (CH) or 0.98 Å (CH3) and Uiso(H) = 1.2Ueq(C) or 1.5Ueq(methyl C)]. Oxygen-bound H atoms 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 ClO4- anion displayed relatively large displacement factors and low electron density peaks so that the anion appears to be highly disordered. Atoms O3, O4 and O5 were modelled isotropically as disordered over two sites with a site occupancy factor of 0.51 (1) for the major component. The highest peak (1.05 e Å-3) and the deepest hole (-0.69 e Å-3) in the difference Fourier map are located 0.81 Å and 0.66 Å from the atoms O3A and O5B, respectively.Mononuclear MnII complexes of 2,2'-bipyrimidine (bpym; C8H6N4) ligand and ClO4- anions, such as [Mn(bpym)2(H2O)2](ClO4)2.2H2O (Hong et al., 1996) and [Mn(bpym)2(CH3CN)(H2O)][Mn(bpym)2(H2O)2](ClO4)4.2H2O (Ha, 2011), have been investigated previously.
The π-π interactions between adjacent pyrimidine rings are present, the shortest ring centroid-centroid distance being 3.688 (2) Å.
of the title compound, [Mn(bpym)2(H2O)2](ClO4)2.2CH3NO2.H2O, contains one half of a cationic MnII complex, a ClO4 anion, a nitromethane solvent molecule and one half of a water molecule (Fig. 1). The complex and the solvent water molecule are located on the twofold rotation axis running in the [010] direction and passing through the atoms Mn1 and O8. In the complex, the MnII ion has a distorted cis-N4O2 octahedral coordination geometry defined by four N atoms of the two chelating bpym ligands and two O atoms of water ligands. The tight N—Mn—N chelating angles contribute the distortion of the ocataheron [<N1—Mn1—N4 = 72.59 (10)°], which result in non-linear trans axes [<O1—Mn1—N4i = 161.83 (10)° and <N1—Mn1—N1i = 174.05 (14)°); symmetry code i: -x,y,1/2 - z]. The Mn—N bond lengths are almost equivalent and slightly longer than the Mn—O bond (Table 1). The dihedral angle between the least-squares planes of the two bpym ligands [maximum deviation = 0.087 (3) Å] is 75.44 (4)°. In the the complex molecules, anions and solvent molecules are linked by intermolecular O—H···N, O—H···O and C—H···O hydrogen bonds (Fig. 2, Table 2). The complexes are stacked in columns along the b axis. When viewed down the c axis, the successive complexes stack in the opposite manner. In the columns, several intermolecularFor related structures of 2,2'-bipyrimidine MnII complexes, see: Hong et al. (1996); Ha (2011).

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 and ClO4- anions, such as [Mn(bpym)2(H2O)2](ClO4)2.2H2O (Hong et al., 1996) and [Mn(bpym)2(CH3CN)(H2O)][Mn(bpym)2(H2O)2](ClO4)4.2H2O (Ha, 2011), have been investigated previously.
The asymmetric unit of the title compound, [Mn(bpym)2(H2O)2](ClO4)2.2CH3NO2.H2O, contains one half of a cationic MnII complex, a ClO4 anion, a nitromethane solvent molecule and one half of a water molecule (Fig. 1). The complex and the solvent water molecule are located on the twofold rotation axis running in the [010] direction and passing through the atoms Mn1 and O8. In the complex, the MnII ion has a distorted cis-N4O2 octahedral coordination geometry defined by four N atoms of the two chelating bpym ligands and two O atoms of water ligands. The tight N—Mn—N chelating angles contribute the distortion of the ocataheron [<N1—Mn1—N4 = 72.59 (10)°], which result in non-linear trans axes [<O1—Mn1—N4i = 161.83 (10)° and <N1—Mn1—N1i = 174.05 (14)°); symmetry code i: -x,y,1/2 - z]. The Mn—N bond lengths are almost equivalent and slightly longer than the Mn—O bond (Table 1). The dihedral angle between the least-squares planes of the two bpym ligands [maximum deviation = 0.087 (3) Å] is 75.44 (4)°. In the crystal structure, the complex molecules, anions and solvent molecules are linked by intermolecular O—H···N, O—H···O and C—H···O hydrogen bonds (Fig. 2, Table 2). The complexes are stacked in columns along the b axis. When viewed down the c axis, the successive complexes stack in the opposite manner. In the columns, several intermolecular π-π interactions between adjacent pyrimidine rings are present, the shortest ring centroid-centroid distance being 3.688 (2) Å.
