Abstract
Both title compounds, bis(triphenylphosphine)iminium tetrabromooxomoly bdate(V), (C36H30NP2) [MoOBr4], and tetraphenylphosphonium aquatetraio dooxomolybdate(V), (C24H20P)[MoOI4(H2O)], form by air oxidation of sol utions containing the [Mo3X12](3-) anion, i.e. the bis(triphenylphosph ine)iminium salt for X = Br and the tetraphenylphosphonium salt for X = I. Both anions have been reported previously in different salts. The geometry of the tetrabromooxomolybdate(V) anion is square pyramidal w ith the oxo ligand occupying the apical position, whereas the aquatetr aiodooxomolybdate (V) anion can be described as a pseudo-octahedron wi th the aqua and oxo ligands occupying trans positions.
