Abstract

From weakly acidified solutions of sodium molybdate by addition of tetrabutylammonium ions an iso-octamolybdate [N(C4H9)4]4Mo8 O26 is formed whose anion has a structure different from the known alkali or ammonium octamolybdates. Single crystals are obtainable by reaction in organic solvents. The IR and Raman spectra are presented. The decomposition of the anion by aging in dichloroethane in solution was investigated by UV spectroscopy. This study offers new aspects concerning the mechanism of polymolybdate ion formation.
