Funktionalisierte 1,1-Ethendithiolate als Liganden, II / Functionalized 1,1-Ethene Dithiolates as Ligands, II

Synthesis, Characterization, and Tautomerism of Four Novel Copper(I) Complexes from 3-Hydroxy-3-(p-R-phenyl)-2-propenedithioic Acids

“…Weigand, Coucouvanis, , and Lih 3 have proposed two possible coordination modes ( V and VI ) for these kinds of ligands (Chart ); however, only a few examples displaying S,S-coordination have been reported for Ni(II), Pd(II), Pt(II), ,, and Fe(0) , complexes (Chart ).

1,1-Ethylenedithiolato Complexes of Palladium(II) and Platinum(II) with Isocyanide and Carbene Ligands

“…11 The 1,1-ethylenedithiolato ligands have also been used to stabilize unusually high oxidation states [12][13][14] or to facilitate the syntheses of clusters. [15][16][17][18][19][20][21] Most 1,1-ethylenedithiolato complexes are mononuclear 7-9,12-14, [22][23][24][25][26][27] although some polynuclear complexes [28][29][30][31] including clusters 15,18,19,[32][33][34][35][36][37] are known.…”

“…Although a few 1,1-ethylenedithiolato complexes of Cr, Mn, Fe, ,− Co, ,, Ir, Ag, , and Zn ,, have been reported, the most abundant are those of Ni, ,,,,− Pd, ,,,− Pt, − ,,,,,− Cu, ,,,, and Au, − ,,− which, in the majority of cases, contain the i -mnt ligand. This is also the case for gold complexes.…”
