Abstract
The zinc(II) complex, Zn(3,5-di- t-butyl-4-hydroxybenzene-dithiocarboxylate) 2(pyridine) ( 3) was obtained by the reaction of Zn(CH 3CN) 4(BF 4) 2 with the sodium salt of 3,5-di- t-butyl-4-hydroxybenzene-dithiocarboxylate ( 1) with subsequent recrystallization from pyridine. The latter salt ( 1) was prepared by the deprotonation of 2,6-di- t-butylphenol with NaH in THF, followed by reaction with carbon disulfide at ambient temperature. The structure of complex 3 was established by X-ray crystallography and shown to be of a distorted trigonal bipyramidal geometry with one sulfur atom from each of the dithiocarboxylate ligands occupying the axial sites. By way of contrast, Na(2,4-di- t-butylphenolate) was found to react with CS 2 to afford the xanthate derivative, Na(O-2,4-di- t-butylphenyldithiocarbonate) ( 4).
