L,3-DITHIOLE-2-THIONE-4,5-DITHIOLATE

The structure of [Mo3S4(dmit)3] (dmit=l,3-dithiole-2-thione-4,5-dithiolate) represents one of the rare examples of M3S4 clusters where each metal atom appears as pentacoordinate instead of its more common type-I structure octahedral environment [39]. Complexes [M3Q4(dmit)3] (M = Mo, W Q = S, Se) degrade in air with an almost quantitative yield and afford a series of M(V) dimers of formula [M202(//-Q)2(dmit)2] where the oxygen atoms are in a syn configuration.

K[Os(N)(CH2SiMe3)2(bdt)] and (NBu4)[Os(N)(CH2SiMe3)2(dmit)] (dmit= l,3-dithiol-2-thione-4,5-dithiolate) have also been reported. " ... [Pg.762]

A very important ion related to thiocarbonyl compounds is the l,3-dithiole-2-thione-4,5-dithiolate (isotrithione-dithiolate, dmit) (159), introduced by Steimecke and coworkers681 in 1975. It is formed as the main product by chemical (with sodium or potassium)681,682 or electrochemical reduction683 of CS2 in DMF (reaction 166). [Pg.1475]

Attempts to follow a published procedure for the preparation of l,3-dithiole-2-thione-4,5-dithiolate salts [1], involving reductive coupling of carbon disulfide with alkali metals, have led to violent explosions with potassium metal, but not with sodium [2]. However, mixtures of carbon disulfide with potassium—sodium alloy, potassium, sodium, or lithium are capable of detonation by shock, though not by heating. The explosive power decreases in the order given above, and the first mixture is more shock-sensitive than mercury fulminate [3]. [Pg.247]
