Bis[1,1′-(butane-1,4-diyl)diimidazolium] δ-octamolybdate(VI)

Abstract

Key indicators: single-crystal X-ray study; T = 293 K; mean (C-C) = 0.004 Å; R factor = 0.021; wR factor = 0.048; data-to-parameter ratio = 17.3.The title compound, (C 10 H 16 N 4 ) 2 [-Mo 8 O 26 ], was synthesized by a hydrothermal reaction. The structure consists of a centrosymmetric -octamolybdate anion and two 1,1 0 -(butane-1,4-diyl)bis(imidazolium) cations for charge balance. The anions and cations are linked by N-HÁ Á ÁO hydrogen bonds, generating a three-dimensional supramolecular structure.
