 For example, with Ni(II) sources, it forms [Ni(MoS4)2]2−.Much of the chemistry of the thiomolybdate results from studies on salts of quaternised organic cations, such as [NEt4]2[MoS4] and [PPh4]2[MoS4] (Et = C2H5, Ph = C6H5).These organic salts are soluble in polar organic solvents such as acetonitrile and dmf.
