New Mixed Ligand Complexes with Perthio CarboxylatesSolutions of O-methyl-1,1-dithiooxalate (i-dtoMe) and metal(II)-chlorides (NiII, PdII) in the molar ratio 2:1 react with equimolar amounts of homonuclear bischelates of other 1,1- and 1,2-dithio-compounds L (L = i-mnt, Etxan, dto) to mixed ligand complexes M(ptoMe)L with spontaneous convertion of the 1,1-dithiooxalate into the corresponding perthio ligand (ptoMe) by sulfur insertion. Tetraphenylphosphonium-(1,1-dicyanoethene-2,2-dithiolato)(O-methyl-1,1 -perthio-oxalato)niccolat(II), Ph4P[Ni(i-mnt)(ptoMe)], crystallizes in the monoclinic space group P21/n with a = 11.019(2) Å, b = 13.648(3) Å, c = 20.882(3) Å, β = 92.565(7)°. The formation of the perthio ligand is confirmed by 13C-NMR.

Tetraphenylphosphonium (1,1-dicyanoethen-2,2-dithiolato)(O-methyl-1,1-perthiooxalato)niccolat(II), Ph4P[Ni(i-mnt)(ptoMe)], kristallisiert in der monoklinen Raumgruppe P21/n mit a = 11,019(2) Å, b = 13,648(3) Å, c = 20,882(3) Å, β = 92,565(7)°. Die Bildung des Perthioliganden konnte mittels 13C-NMR bestätigt werden.
