Abstract

The title compound, (C6H8N)4[Mo8O26], has been prepared and its crystal structure determined by X-ray crystallography. The compound is triclinic,P¯1,Z=1 witha=10.167(1),b=10.745(1),c=10.027(8) Å,α=85.05(1),β=106.73(3), λ=107.75(1)°,V=999.1(7) Å3,F(000)=748,D x=2.59 andD o=2.61(1) Mg/m3. The [Mo8O26]4− anion shows slight differences in several bond lengths and angles when compared with other related octamolybdates. The planar cations are connected to the polyanions through bifurcated hydrogen bonds. The MoO6 octahedra are distorted and the distortion has been evaluated using three different equations. The spectroscopic study shows that the cations are protonated and the polyanion presents the well-known infrared spectrum for octamolybdates.
