A mixture of Mncl2 (0.5 mmol, 0.06 g) and 2-propyl-1H-imidazole-4,5-dicarboxylic acid(0.5 mmol, 0.99 g) in 15 ml of H2O solution was sealed in an autoclave equipped with a Teflon liner (20 ml) and then heated at 433k for 4 days. Crystals of the title compound were obtained by slow evaporation of the solvent at room temperature.
Water H atoms were located in a difference Fourier map and were allowed to ride on the parent atom, with Uiso(H) = 1.5Ueq(O). Carboxyl H atoms were located in a difference map and refined with distance restraints, Uiso(H) = 1.5Ueq(O). Other H atoms were placed at calculated positions and were treated as riding on parent atoms with C—H = 0.96 (methyl), 0.97 (methylene) and N—H = 0.86 Å, Uiso(H) = 1.2 or 1.5Ueq(C,N). The propyl groups of H3pimda are disordered over two sites with refined occupancies of 0.759 (5):0.241 (5) and 0.545 (7):0.455 (7). C—C distance restraints of disordered components were applied. The O3W water molecule is located close to an inversion center, its occupancy factor was refined to 0.49 (1) and was fixed as 0.5 at the final refinements.
There is considerable interest in the design and synthesis of metal-organic frameworks (MOFs) due to their potential applications in conductivity, luminescence, catalysis, magnetism and sensors as well as fascinating architectures and topologies. 2-propyl-1H-imidazole-4,5-carboxylate(H3pimda) ligand as one derivative of H3IDC with efficient N,O-donors has been used to obtain new metal-organic complexes by our research group, such as poly[diaquabis(5-carboxy-2-propyl-1H-imidazole-4-carboxylato-k3 N3, O4,O5)calcium(II)](Song et al., 2010), [diaquabis(5-carboxy-2-propyl-1H-imidazole-4-carboxylato-k2N3,O4) manganese(II)]N,N-dimethylformamide(Yan et al., 2010), [Diaquabis(5-carboxy-2-propyl-1H-imidazole-4-carboxylato-k2 N3,O4)nickle(II)]N,N-dimethylformamide disolvate(Li et al., 2010), Diaquabis(4-carboxy-2-propyl-1H-imidazole-5-carboxylato- k2N3,O4)copper(II) N,N-dimethylformamide disolvate(He et al., 2010) and Diaquabis(5-carboxy-2-propyl-1H-imidazole- 4-carboxylato-k2N3,O4)nickle(II) tetrahedrate(Fan et al., 2010). In this paper, we report the structure of a new Mn(II) complex obtained under hydrothermal conditions.
As illustrated in figure 1, the title complex molecule is isomorphous with Ni(II) analog(Fan et al., 2010). Similar structural description applies to the present isomorphous complex. The MnII is six-coordinated by two N,O-bidentate H3pimda anions and two water molecules, and exhibits a distorted octahedral geometry. The carboxylic acid ligand bears a formal charge of -1, and the free carboxylate atoms O1 and O4, O6 and O7 form intramolecular hydrogen bonds, respectively. The dihedral angle between the two imidazole rings is 77.2 (8) %A. In the crystal structure, the three-dimensional supramolecular framework is stabilized by extensive O—H···O and N—H···O hydrogen bonds involving the free water molecules, the coordinated water molecules, the carboxy O atoms and the protonated N atoms of H3pimda. The propyl groups of H3pimda are disordered over two sets of sites with refined occupiencies of 0.759 (5):0.241 (5) and 0.545 (7):0.455 (7).

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. |

There is considerable interest in the design and synthesis of metal-organic frameworks (MOFs) due to their potential applications in conductivity, luminescence, catalysis, magnetism and sensors as well as fascinating architectures and topologies. 2-propyl-1H-imidazole-4,5-carboxylate(H3pimda) ligand as one derivative of H3IDC with efficient N,O-donors has been used to obtain new metal-organic complexes by our research group, such as poly[diaquabis(5-carboxy-2-propyl-1H-imidazole-4-carboxylato-k3 N3, O4,O5)calcium(II)](Song et al., 2010), [diaquabis(5-carboxy-2-propyl-1H-imidazole-4-carboxylato-k2N3,O4) manganese(II)]N,N-dimethylformamide(Yan et al., 2010), [Diaquabis(5-carboxy-2-propyl-1H-imidazole-4-carboxylato-k2 N3,O4)nickle(II)]N,N-dimethylformamide disolvate(Li et al., 2010), Diaquabis(4-carboxy-2-propyl-1H-imidazole-5-carboxylato- k2N3,O4)copper(II) N,N-dimethylformamide disolvate(He et al., 2010) and Diaquabis(5-carboxy-2-propyl-1H-imidazole- 4-carboxylato-k2N3,O4)nickle(II) tetrahedrate(Fan et al., 2010). In this paper, we report the structure of a new Mn(II) complex obtained under hydrothermal conditions.
As illustrated in figure 1, the title complex molecule is isomorphous with Ni(II) analog(Fan et al., 2010). Similar structural description applies to the present isomorphous complex. The MnII is six-coordinated by two N,O-bidentate H3pimda anions and two water molecules, and exhibits a distorted octahedral geometry. The carboxylic acid ligand bears a formal charge of -1, and the free carboxylate atoms O1 and O4, O6 and O7 form intramolecular hydrogen bonds, respectively. The dihedral angle between the two imidazole rings is 77.2 (8) %A. In the crystal structure, the three-dimensional supramolecular framework is stabilized by extensive O—H···O and N—H···O hydrogen bonds involving the free water molecules, the coordinated water molecules, the carboxy O atoms and the protonated N atoms of H3pimda. The propyl groups of H3pimda are disordered over two sets of sites with refined occupiencies of 0.759 (5):0.241 (5) and 0.545 (7):0.455 (7).
