CONTRIBUTIONS TO THE CHEMISTRY OF THIOCOMPLEXES - NEW COMPLEX-COMPOUNDS OF NI(II), PD(II), PT(II) AND AU(III) WITH 3-(2'-THIOTHENOYLAMINO)DIBENZOFURAN

New complex compounds of Ni(II), Pd(II) and Au(III) with 3-(2'thiothen oylamino)dibenzofuran, (TTADBF) are described. Elemental analysis, UV, visible, IR spectra and conductivity measurements suggest that the co mpounds are of [MLCl(2)] type (M = Ni(II), Pd(II), L = TTADBF and [MLC l(2)]Cl type (M = Au(III), L = TTADBF). The chemical bond implies a su lphur and a nitrogen atom of the ''thione'' group in coordination to t he metal. Electronic spectra point to a plane-square geometry of the c omplexes.
