Abstract
Compositions of the formula [(Cat.sup.n)].sub.3/n [Co(MoS.sub.4).sub.2 ] wherein Cat is a mono, di or trivalent cation and n is 1, 2 or 3, respectively, have been prepared in non-aqueous media. The [Co(MoS.sub.4).sub.2 ].sup.3- anion has the general structure ##STR1## Cat is preferably an alkyl substituted quaternary ammonium compound.
Claims15
The composition of matter containing the [Co(MoS.sub.4).sub.2 ].sup.3- trianion of the structure ##STR6## and one or more cations with a charge sufficient to balance the trinegative charge of said trianion.
The composition of matter of the formula [(Cat.sup.n).sub.3/n ][Co(MoS.sub.4).sub.2 ] wherein the [Co(MoS.sub.4)].sup.3- trianion has the structure ##STR7## wherein the cobalt is in the 1+ oxidation state and wherein Cat is a mono, di or trivalent cation and n is 1, 2 or 3, respectively.
The composition of matter of the formula [(Cat.sup.n).sub.3/n ][Co(MoS.sub.4).sub.2 ] wherein the cobalt is tetrahedrally coordinated with four sulfur atoms with each of the two tetrathiomolybdate groups providing two of said four sulfur atoms, wherein Cat is a mono, di or trivalent onium cation and wherein n is 1, 2 or 3, respectively.
