The title compound, (C4H12N2)3[PMo12O40] or (H2pip)3[PMo12O40] (pip is piperazine), was prepared under hydrothermal conditions. The contains one-sixth of a mixed-valent Mo(V,VI) pseudo-Keggin-type [PMo12O40]6− anion and half a piperazinediium cation, (H2pip)2+. The discrete Keggin-type [PMo12O40]6- anion has and the three (H2pip)2+ cations each have at the centres of the molecules. The central P atom is on special position , which is a roto-inversion position and generates the disorder of the PO4 tetrahedron. Furthermore, six doubly bridging oxide groups are also disordered with an occupancy factor of 0.5 for each O atom. The anions and cations are linked by an extensive network of intermolecular N—H⋯O and C—H⋯O hydrogen bonds.

A mixture of KH2PO4.2H2O(0.70 g, 5 mmol), MoO3.2H2O (0.45 g, 2.5 mmol), pip (0.43 g, 5 mmol), H3BO3 (0.31 g, 5 mmol) and 18 ml water was stirred for 2 h in air; it was adjusted to pH = 1 with HCl solution (18 wt %) and was heated in a 25 ml stainless steel reactor with a Teflon-liner at 180°C for 5 days, and then cooled to room temperature. Black polyhedron crystals were isolated with 71% yield (based on Mo). Elemental analysis for 1: Anal. Calcd: C, 6.91; H, 1.74; N, 4.03; found: C, 6.96; H, 1.67; N, 4.11.

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. |

Polyoxometalates (POMs) comprise a rich and diverse family of metal oxygen clusters made up of early transition metals (primarily including W, Mo and V) with unique redox, acidic, magnetic and catalytic properties (Pope & Müller, 1991; Hill, 1998). The Keggin-type structure was of epoch-making significance in the history of POMs chemistry (Kurth, 2001). The Keggin-type polyanions, [PMo12O40]3-, have been indicated as excellent building blocks to construct novel compounds (Li et al., 2007; Yuan et al., 2008).
The structure of the title compound consists of a discrete polyoxoanion [PMo12O40]6- and three diprotonated piperazine molecules. The heteropolyoxoanion [PMo12O40]6- has a roto-inversion symmetry with the P1 atom located on the 3 centre. The pseudo-Keggin unit [PMo12O40]6- may be viewed as a shell of {Mo12O36} encapsulating a disordered {PO4} moiety, present at its center and responsible for the local tetrahedral geometry. The central P atom is surrounded by a cube of eight oxygen (six O7 and two O8) atoms with each of them half occupied due to the inversion symmetry at P1, and each oxygen of the {PO4} group covalently bonded to three different molybdenum centers of the shell (Fig. 1). All Mo centers possess similar distorted octahedral geometry MoO6 defined by one terminal oxygen atom, four doubly bridging oxo-groups and one central oxygen atom. Six doubly bridging oxo-groups (O3, O30, O4, O40, O5 and O50) are disordered with occupancy factor 0.5.
Extensive hydrogen bonding interactions help to stabilize the structure (Table 1). Each (H2pip)2+ cation donates eight N—H···O hydrogen bonds to eight bridging oxygen atoms from two [PMo12O40]6- anions and two ones to two terminal oxygen atoms from the other two [PMo12O40]6- anions. Each [PMo12O40]6- anion joins twelve (H2pip)2+ cations to generate a three-dimensional supramolecular network structure (Fig.2).
Result of bond valence sum (Brown & Altermatt, 1985) calculation for Mo centers gives the average value 5.71 (5.52 for Mo1 and 5.89 for Mo2) in good agreement with the expected value of 5.75, which reveals that there exist three MoV and nine MoVI atoms in the Keggin-type compound. The three classes of Mo—O average distances are 1.663, 1.925 and 2.482 Å, being obviously larger than the corresponding distances in [PMo12O40]5- (1.638, 1.891 and 2.443 Å) (Han et al., 2005).
