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