Bis-[4,4'-(propane-1,3-di-yl)-dipiperidin-ium] β-octa-molybdate(VI).

The title compound, bis-[4,4'-(propane-1,3-di-yl)-dipiperidin-ium] β-octa-molybdate(VI), (C(13)H(28)N(2))(2)[Mo(8)O(26)], was produced by hydro-thermal reaction of an acidified aqueous solution of Na(2)MoO(4)·2H(2)O and 4,4'-trimethyl-ene-dipiperidine (L). The structure of the title compound consists of β-octa-molybdate(VI) anion clusters and protonated [H(2)L](2+) cations. The octa-molybdate anion is located around an inversion center. N-H⋯O hydrogen bonds between the cations and anions ensure the cohesion of the structure and result in a three-dimensional network.

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.
