CONTRIBUTIONS TO THE CHEMISTRY OF THIOCOMPLEXES - COMPLEX-COMPOUNDS OF NI(II), PD(II) AND PT(II) WITH 6-THIOACETYLAMINO-2,3-DICHLORO-QUINOXALINE

The paper reports new complexes of Ni(II), Pd(II) and Pt(II) with 6-th ioacetylamino-2,3-dichloro-quinoxaline (TAAQ). The compounds were char acterized by elemental analysis and by IR, visible and UV spectra. The results show that the complexes are of the type [MLCl2] in which M is Ni(II), Pd(II) and Pt(II) and L is the ligand; it acts in the ,,thiok eto'' form as a bidentate ligand. Electronic spectra show a plane-squa re geometry of the complexes.
