The title compound, (C2H10N2)3(C2H9N2)2[Mo5(HPO4)2O15]·10H2O, was prepared under hydrothermal conditions at pH 5.0. The structure contains mono- and diprotonated ethylenediamine cations, [Mo5O15(HPO4)2]4− anions and uncoordinated water molecules. The [Mo5O15(HPO4)2]4− heteropolyoxometallate anion is made up of five MoO6 octahedra sharing an edge and forming a ring, which is closed by common corners of the terminal MoO6 octahedron. The ring is topped on both sides by two slightly distorted PO4 tetrahedra, sharing three corners with three MoO6 octahedra. The terminal oxygen atoms of the PO4 units are protonated. Together with the anions, the water molecules and the ethylenediammonium cations are involved in N—H⋯O and O—H⋯O hydrogen bonding, forming a three-dimensional supramolecular network.

Compound (I) was obtained under hydrothermal conditions. (NH4)6Mo7O24˙4H2O (0.37 g), H3PO4 (85%, 0.2 mL) Mn(OAc)2.H2O (0.12 g) were added in water (15 mL). The pH value was adjusted to 5.0 by ethylenediamine, and the mixture was heated at 453 K for 5 d. Blue crystals were obtained with 15% yield (based on Mo). Elemental analysis for C5H36Mo5N5O28P2: Found: C 5.36, H 3.23%, N 6.48, P 5.79, Mo 42.07%; calcd. C 5.19, H 3.11, N 6.06, P 5.36 Mo 41.52%.
The H atoms attached to carbon atoms were positioned geometrically and were treated as riding on their parent atoms, with a C—H distance of 0.97 Å and Uiso(H) = 1.2Ueq(C). The hydrogen atoms of the water molecules, ammonium functions and O1 and O5 atoms of the phosphate groups were located in difference maps and were refined by using the 'DFIX' command with O—H = 0.85 (2) Å and N—H = 0.89 (2) Å with Uiso(H) = 1.2Uiso(O) and Uiso(H) = 1.5Uiso(O), respectively. The distance of the highest peak is 0.87 Å from O14, and the distance of the deepest hole is 1.00 Å from Mo1.
Numerous polyoxometalates (POMs) have been synthesized and characterized because of their interesting structures and potential applications (Coronado et al., 1998; Niu et al., 2009; Ruether et al., 2003). POM syntheses are usually performed under hydrothermal conditions and one or more of the reaction parameters, such as temperature, pH, stoichiometry, reaction time, can influence the reaction product. Thus the rational synthesis of POMs is still a great challenge. In a previous study, the compounds (C2H10N2)2[Mo5O15(HPO4)2] and the title compound, (C2H10N2)3(C2H9N2)2[Mo5O15(HPO4)2].10H2O, (I), were synthesized at pH 3.0 and 5.0, respectively. Because compound (C2H10N2)2[Mo5O15(HPO4)2] has been reported in detail (Sun et al., 2003), we only report the structure of compound (I).
The
of compound (I) contains one and a half ethylenediammonium cations, one (2-aminoethyl)ammonium cation, five lattice water molecules and one heteropolyoxometallate anion [Mo5O15(HPO4)2]4-. The latter is made up of five MoO6 octahedra sharing an edge and forming a ring which is closed by common corners of the terminal octahedron. The rings are topped on both sides by two asymmetric PO4 tetrahedra, sharing three corners with three MoO6 octahedra (Fig. 1). According to the results of valence bond calculations (Brown, 2002), both terminal oxygen atoms of the two PO4 tetrahedra are protonated: (bond valence sums are 1.24 for O1 and 1.29 for O5). The shortest Mo—O bond lengths are observed for terminal oxygen atoms with a mean distance of 1.708 Å, and those involving oxygen atoms of PO4 are the longest bond with a mean bond lengths of 2.292 Å. Mo—O bond lengths involving other oxygen atoms range from 1.917Å to 1.966 Å. All those bond lengths are similar to other reported heteropolyoxometallate anions (Sun et al. (2003) for [Mo5O15(HPO4)2]4-, and Gong et al. (2006) and Skibsted et al. (2000) for [Mo5O15(PO4)2]6-).As shown in Fig. 2, lattice water molecules, the protonated ethylenediamine cations and the [Mo5O15(HPO4)2]4- anions are bonded with each other via O—H···O and N—H···O hydrogen bonds to form a three-dimensional network. The geometric parameters of hydrogen bonding are listed in Table 1.

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. |

Numerous polyoxometalates (POMs) have been synthesized and characterized because of their interesting structures and potential applications (Coronado et al., 1998; Niu et al., 2009; Ruether et al., 2003). POM syntheses are usually performed under hydrothermal conditions and one or more of the reaction parameters, such as temperature, pH, stoichiometry, reaction time, can influence the reaction product. Thus the rational synthesis of POMs is still a great challenge. In a previous study, the compounds (C2H10N2)2[Mo5O15(HPO4)2] and the title compound, (C2H10N2)3(C2H9N2)2[Mo5O15(HPO4)2].10H2O, (I), were synthesized at pH 3.0 and 5.0, respectively. Because compound (C2H10N2)2[Mo5O15(HPO4)2] has been reported in detail (Sun et al., 2003), we only report the structure of compound (I).
The asymmetric unit of compound (I) contains one and a half ethylenediammonium cations, one (2-aminoethyl)ammonium cation, five lattice water molecules and one heteropolyoxometallate anion [Mo5O15(HPO4)2]4-. The latter is made up of five MoO6 octahedra sharing an edge and forming a ring which is closed by common corners of the terminal octahedron. The rings are topped on both sides by two asymmetric PO4 tetrahedra, sharing three corners with three MoO6 octahedra (Fig. 1). According to the results of valence bond calculations (Brown, 2002), both terminal oxygen atoms of the two PO4 tetrahedra are protonated: (bond valence sums are 1.24 for O1 and 1.29 for O5). The shortest Mo—O bond lengths are observed for terminal oxygen atoms with a mean distance of 1.708 Å, and those involving oxygen atoms of PO4 are the longest bond with a mean bond lengths of 2.292 Å. Mo—O bond lengths involving other oxygen atoms range from 1.917Å to 1.966 Å. All those bond lengths are similar to other reported heteropolyoxometallate anions (Sun et al. (2003) for [Mo5O15(HPO4)2]4-, and Gong et al. (2006) and Skibsted et al. (2000) for [Mo5O15(PO4)2]6-).
As shown in Fig. 2, lattice water molecules, the protonated ethylenediamine cations and the [Mo5O15(HPO4)2]4- anions are bonded with each other via O—H···O and N—H···O hydrogen bonds to form a three-dimensional network. The geometric parameters of hydrogen bonding are listed in Table 1.
