A series of N-heterocyclic carbene (NHC) supported group 12 acetate complexes were prepared and their use as building blocks toward soluble group 12 sulfide precursors was explored. The highly moisture-sensitive NHC-ligated zinc dithiolato complex [(IPr)Zn(SSiMe3)2] was also synthesized [IPr=1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidene], and its partial hydrolysis gave the dianionic zinc sulfide cluster [Zn3(μ3-S)(μ2-SSiMe3)3(SSiMe3)3]2−, which contained a rare example of a Zn3S structural motif. This preliminary observation indicates that the future growth of related metallosulfide clusters from [(IPr)Zn(SSiMe3)2] should be possible.
