The 8H7N3)3]2[PMo12O40]·6H2O, consists of a complex [Mn(C8H7N3)3]2+ cation, half of a mixed-valent MoV,VI α-Keggin-type [PMo12O40]4− heteropolyanion, and three uncoordinated water molecules. The Mn2+ cation is surrounded by six N atoms from three chelating 3-(2-pyridyl)-1H-pyrazole ligands in a distorted octahedral coordination. In the heteropolyanion, two O atoms of the central PO4 group ( symmetry) are equally disordered about an inversion centre. N—H⋯O and O—H⋯O hydrogen bonding between the cations, anions and the uncoordinated water molecules leads to a consolidation of the structure.

A mixture of 3-(2-pyridyl)-1H-pyrazole (0.5 mmoL 0.07 g), sodium molybdate (0.4 mmoL, 0.10 g), manganese(II) sulfate monohydrate (0.3 mmol, 0.05 g), and dipotassium hydrogenphosphate (0.22 mmol, 0.05 g) in 10 ml distilled water was sealed in a 25 ml Teflon-lined stainless steel autoclave and was kept at 433 K for three days. Pink crystals suitable for the X-ray experiment were obtained. Anal. C48H54Mn2Mo12N18O46P: C, 19.80; H, 1.82; N, 8.66. Found: C, 19.71; H, 1.74; N, 8.58 %.

TGA curve shows that the lattice water molecules and the organic ligands seperate above 372 and 683 K, respectively. The overall thermal decomposition process can be described by the followed equation: 4C48H54Mn2Mo12N18O46P + 325O2 = 108H2O + 192CO2 + 36N2O5 + 8MnO + 2P2O5 + 48MoO3
All hydrogen atoms bound to aromatic carbon atoms were refined in calculated positions using a riding model with a C—H distance of 0.93 Å and Uiso = 1.2Ueq(C). Hydrogen atoms attached to aromatic N atoms were refined with a N—H distance of 0.86 Å and Uiso = 1.2Ueq(N). The hydrogen atoms of the three uncoordinated water molecules could not be located unambiguously from difference Fourier maps, probably due to disorder of the water molecules. Thus the structure was refined without the H atoms of the water molecules (which includes the water O atoms O1W, O2W, O3W). In the PO4 unit, the two oxygen atoms (O19 and O21) are equally disordered about the inversion centre. In the final difference Fourier map the highest peak is 2.86 Å from atom O2w and the deepest hole is 1.09 Å from atom O9. The highest peak is located in the voids of the
and may be associated with an additional water molecule. However, of this position did not result in a reasonable model. Hence this position was also excluded from the final refinement.The design and synthesis of polyoxometalates has attracted continuous research interest not only because of their appealing structural and topological novelties, but also due to their interesting optical, electronic, magnetic, and catalytic properties, as well as their potential medical applications (Pope & Müller, 1991). In our research group, organic
such as 3-(2-pyridyl)pyrazole and pyrazine, are used to effectively modify polyoxomolybdates under hydrothermal condictions (Zhang, Dou et al., 2009; Zhang, Wei et al., 2009). Here, we describe the synthesis and structural characterization of the title compound.As shown in Figure 1, the
of the title compound consists of three subunits, viz. of a complex [Mn(C8H7N3)3]2+ cation, a heteropolyanion [PMo12O40]4- and of three uncoordinated water molecules. The Mn(II) ion is distorted octahedrally coordinated by six N atoms from three chelating 3-(2-pyridyl)-1H-pyrazole ligands. The Mn—N bond lengths are in the range of 2.224 (6)—2.283 (5) Å.The heteropolyanion [PMo12O40]4- is an one electron-reduced derivative of [PMo12O40]3-, similar to other reported representatives (Artero & Proust, 2000; Kurmoo et al., 1998; Niu et al., 1999). The employed organic ligand appears to adjust the pH value, and additionally supplies reducing electrons, which is a commonly observed feature of hydrothermal syntheses when organic
are used to prepare various hybrid materials, zeolites or metal phosphates (Yang et al., 2003).In the Keggin-type heteropolyanion, each Mo atom is surrounded by six O atoms and the P atom is located at the centre of the anion. There are four kinds of O atoms present in the anion according to their coordination environments: Oa (O atoms in the disordered PO4 tetrahedron), Ob (bridging O atoms between two triplet groups of MoO6 octahedra), Oc (bridging O atoms within one triplet group of MoO6 octahedra) and Od (terminal O atoms). The P—O bond distances are in the normal range of 1.495 (7)—1.562 (6) Å. The Mo—O bond distances vary widely from 1.644 (4) to 2.517 (6) Å. The shortest Mo—O bonds are in the range of 1.644 (4)—1.666 (4) Å for the terminal oxygen atoms. The longest Mo—O lengths are in the range of 2.455 (7)—2.517 (6) Å for those oxygen atoms connected with both Mo and P atoms.
N—H···O and O—H···O hydrogen bonding between the cationic and anionic moieties and the uncoordinated water molecules leads to a consolidation of the structure (Fig. 2; Table 2).

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 > 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. |

The design and synthesis of polyoxometalates has attracted continuous research interest not only because of their appealing structural and topological novelties, but also due to their interesting optical, electronic, magnetic, and catalytic properties, as well as their potential medical applications (Pope & Müller, 1991). In our research group, organic amines, such as 3-(2-pyridyl)pyrazole and pyrazine, are used to effectively modify polyoxomolybdates under hydrothermal condictions (Zhang, Dou et al., 2009; Zhang, Wei et al., 2009). Here, we describe the synthesis and structural characterization of the title compound.
As shown in Figure 1, the asymmetric unit of the title compound consists of three subunits, viz. of a complex [Mn(C8H7N3)3]2+ cation, a heteropolyanion [PMo12O40]4- and of three uncoordinated water molecules. The Mn(II) ion is distorted octahedrally coordinated by six N atoms from three chelating 3-(2-pyridyl)-1H-pyrazole ligands. The Mn—N bond lengths are in the range of 2.224 (6)—2.283 (5) Å.
The heteropolyanion [PMo12O40]4- is an one electron-reduced derivative of [PMo12O40]3-, similar to other reported representatives (Artero & Proust, 2000; Kurmoo et al., 1998; Niu et al., 1999). The employed organic ligand appears to adjust the pH value, and additionally supplies reducing electrons, which is a commonly observed feature of hydrothermal syntheses when organic amines are used to prepare various hybrid materials, zeolites or metal phosphates (Yang et al., 2003).
In the Keggin-type heteropolyanion, each Mo atom is surrounded by six O atoms and the P atom is located at the centre of the anion. There are four kinds of O atoms present in the anion according to their coordination environments: Oa (O atoms in the disordered PO4 tetrahedron), Ob (bridging O atoms between two triplet groups of MoO6 octahedra), Oc (bridging O atoms within one triplet group of MoO6 octahedra) and Od (terminal O atoms). The P—O bond distances are in the normal range of 1.495 (7)—1.562 (6) Å. The Mo—O bond distances vary widely from 1.644 (4) to 2.517 (6) Å. The shortest Mo—O bonds are in the range of 1.644 (4)—1.666 (4) Å for the terminal oxygen atoms. The longest Mo—O lengths are in the range of 2.455 (7)—2.517 (6) Å for those oxygen atoms connected with both Mo and P atoms.
N—H···O and O—H···O hydrogen bonding between the cationic and anionic moieties and the uncoordinated water molecules leads to a consolidation of the structure (Fig. 2; Table 2).
