    Abstract

    [Et3NH]4[Mo8O26] reacted with MgCl2 giving the triethylammonum magnesium β-octamolybdate(VI) salt [Et3NH]2[Mg(H2O)6Mo8O26]·2H2O (3) and the triethylammonium hydronium β-octaamolybdate(VI) salt [Et3NH]3[(H3O)Mo8O26·2H2O (4), respectively. A small amount of [Et3NH]2[Mo6O269] was formed as a by-product. The salts 3 and 4 were characterized by X-ray crystallography. The [Mg(H2O)6Mo8O26]2− moiety in 3 is polymeric, with each octahedral [Mg(H2O)6]2+ ion sandwiched between two β[Mo8O26]4− ions, being hydrogen bonded to three terminal MO==O oxygen atoms on one face of each β[Mo8O26]4− ion. The X-ray crystal structure of 4 corresponds to the reported previously. IR and conductivity data are given for 3 and 4.
