Bis[4,4′-(propane-1,3-diyl)dipiperidinium] β-octamolybdate(VI)

Abstract

The title compound, bis[4,4′-(propane-1,3-diyl)dipiperidinium] β-octamolybdate(VI), (C13H28N2)2[Mo8O26], was produced by hydrothermal reaction of an acidified aqueous solution of Na2MoO4·2H2O and 4,4′-trimethylenedipiperidine (L). The structure of the title compound consists of β-octamolybdate(VI) anion clusters and protonated [H2L]2+ cations. The octamolybdate 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.
