Boron, dithiocarbamate complexes

Main group dithiocarbamate complexes are generally prepared by reaction of the appropriate metal halide with the parent (hydrated) group 1 (I A) metal or ammonium dithiocarbamate salt. Few dithiocarbamate complexes of boron and aluminum have therefore been reported aluminum and boron halides are susceptible to hydrolysis, and hydroxide substitution is generally unfavorable. 

A number of crystallographic studies have been carried out (962,963,966). AU show a syn configuration of dithiocarbamate ligands and molybdenum-molybdenum single bonds [R = Et, Mo—Mo 2.817(2) A]. A related complex, [Tp Mo2S2(lt-S)2(S2CNEt2)] (129) (Fig. 103), a byproduct of the reaction of [Tp MoO(S2CNEt2)l with boron sulfide, adopts a similar structure [Mo Mo 2.829(2) A] (918).
