In the title complex, [Mn(C16H14N4O)(C2H5OH)2(H2O)](C6H2N3O7)2·2C2H5OH, the MnII ion is in a distorted octahedral coordination environment, defined by an MnN2O4 donor set. The 1,3-bis(benzimidazol-2-yl)-2-oxapropane ligand is tridentate. In the intermolecular N—H⋯O and O—H⋯O hydrogen bonds link the components into a three-dimensional network. The O atoms of one of the nitro groups are disordered over two sets of sites with refined occupancies of 0.577 (11) and 0.423 (11).

To a stirred solution of 1,3-bis(benzimidazol-2-yl)-2-oxapropane (91.6 mg, 0.2 mmol) in hot ethanol (10 ml), Mn(C6H2N3O7)2 (102.9 mg, 0.2 mmol) in ethanol (5 ml) was added. A yellow crystalline product formed rapidly. The precipitate was filtered off, washed with ethanol and Et2O, and dried in vacuo. The dried precipitate was dissolved in DMF to form a yellow solution into which diethylether was allowed to diffuse at room temperature. The yellow crystals suitable for X-ray diffraction studies were obtained after one week (Yield, 72%).
All H atoms were placed in calculated positions and refined in a riding-model approximation with; C—H = 0.95-0.99 Å, N-H = 0.88Å, O-H = 0.93-0.95Å and Uiso(H) = 1.2 Ueq(C, N) or Uiso(H) = 1.5 Ueq(Cmethyl, O).
Bis-benzimidazoles are known to be strong chelating agents coordinating through both of the C=N group nitrogen atoms. In addition, as a typical multidentate ligand they have polymer-forming characteristics. In bioinorganic chemistry, they have been used extensively to help model the active sites of metalloproteins (Holland & Tolman, 2000). The benzimidazole ring system is present in clinically approved anthelmintics, antiulcers, antivirals, and antihistamines (Harrell, et al., 2004). Recently, there have been reports on benzimidazole derivatives exhibiting antitumor and antimicrobial properties and acting as thrombopoietin receptor agonists (Chang, et al., 2008).
We have attempted to prepare organic-inorganic hybrid materials with manganese salts using 1,3-bis(benzimidazol-2-yl)-2-oxapropane (OBB). Herein, we report the
of the title compound. The of the title compound is shown in Fig. 1. The MnII ion is coordinated in a distorted octahedral coordination environment. The 1,3-bis(benzimidazol-2-yl)-2-oxapropane ligand acts as tridentate. In the intermolecular N—H···O and O—H···O hydrogen bonds link the components of the structure into a three-dimensional network (Fig. 2).For the applications of benzimidazole and bis-benzimidazole compounds, see: Chang et al. (2008); Harrell et al. (2004); Holland & Tolman (2000).

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds 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 > 2sigma(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. |

Bis-benzimidazoles are known to be strong chelating agents coordinating through both of the C=N group nitrogen atoms. In addition, as a typical multidentate ligand they have polymer-forming characteristics. In bioinorganic chemistry, they have been used extensively to help model the active sites of metalloproteins (Holland & Tolman, 2000). The benzimidazole ring system is present in clinically approved anthelmintics, antiulcers, antivirals, and antihistamines (Harrell, et al., 2004). Recently, there have been reports on benzimidazole derivatives exhibiting antitumor and antimicrobial properties and acting as thrombopoietin receptor agonists (Chang, et al., 2008).
We have attempted to prepare organic-inorganic hybrid materials with manganese salts using 1,3-bis(benzimidazol-2-yl)-2-oxapropane (OBB). Herein, we report the crystal structure of the title compound. The asymmetric unit of the title compound is shown in Fig. 1. The MnII ion is coordinated in a distorted octahedral coordination environment. The 1,3-bis(benzimidazol-2-yl)-2-oxapropane ligand acts as tridentate. In the crystal structure, intermolecular N—H···O and O—H···O hydrogen bonds link the components of the structure into a three-dimensional network (Fig. 2).
