• Reactions of the complex ion [Mo<SUB>2</SUB>O<SUB>4</SUB>(C<SUB>2</SUB>O<SUB>4</SUB>)<SUB>2</SUB>(H<SUB>2</SUB>O)<SUB>2</SUB>]<SUP>2−</SUP> (I) have been investigated. On acidification with perchloric acid and hydrochloric acid, complex (I) gave molybdenum(V) aqua-dimer ion [Mo<SUB>2</SUB>O<SUB>4</SUB>(H<SUB>2</SUB>O)<SUB>6</SUB>]<SUP>2+</SUP>, which was converted into the monomeric species [MoOCl<SUB>5</SUB>]<SUP>2−</SUP> in concentrated hydrochloric acid. The initial reaction of complex (I) with mercaptoacetic acid, giving a complex of stoichiometry 1 ligand: 1 Mo, was followed by a slower reaction which probably gave higher complexes. In the reactions with <I>o</I>-aminophenol and 2,2′-bipyridyl, complexes of stoichiometry 1 ligand: 1 Mo and 1 ligand: 2 Mo, respectively, were formed in solutions. The following complexes have been isolated: Mo<SUB>2</SUB>O<SUB>4</SUB>(dtc)<SUB>2</SUB>, Mo<SUB>2</SUB>O<SUB>3</SUB>(dtc)<SUB>4</SUB> (dtc=diethyldithiocarbamate), MoOCl<SUB>3</SUB>. phen (phen=1,10-phenanthroline), and Mo<SUB>2</SUB>O<SUB>3</SUB>Cl<SUB>4</SUB>(bpy)<SUB>2</SUB> (bpy=2,2′-bipyridyl). The infrared and electronic spectra of the complexes and their probable structures are given. The relative ease of replacement of ligands from complex (I) has been discussed.
