Heteropolytopic arsanylarylthiolato ligands: Cis-trans isomerism of nickel(II), palladium(II), and platinum(II) complexes of 1-AsPh 2-2-SHC6H4

Heteropolytopic arsanylthiolato ligands 1-AsPh2-2-SHC 6H4 (AsSH), PhAs(2-SHC6H4) 2 (AsS2H2), and As(2-SHC6H 4)3 (AsS3H3) have been prepared by lithiation-electrophilic substitution procedures. The 2:1 reaction of AsSH with NiCl2?6H2O, Na2[PdCl4], and [PtI2(cod)] (cod = 1,5-cyclooctadiene) in the presence of NEt 3 afforded the square-planar complexes trans-[Ni{(AsS)-k 2S,As}2] (1), cis-[Pd{(AsS)-k2S,As} 2] (2), trans-[Pd{(AsS)-k2S,As}2] (3), and cis-[Pt{(AsS)-k2S,As}2] (4). In the cases of nickel and platinum, only one isomer was isolated. With palladium, initially the cis isomer 2 is formed and undergoes slow isomerization to the trans isomer 3 in solution. Small amounts of the trinuclear complex [{PtI(1-AsPh2-μ-2-S- C6H4-k2S,As)}3] (5) are also formed besides the mononuclear platinum bis-chelate complex 4. Density functional theory calculations support a dissociative mechanism for the isomerization of the palladium(II) complexes.
