Synthesis and crystal structures of trans-dichlorobis{tri(2-methylphenyl)stibine}palladium(II) and trans-dibromobis{tri(2-methylphenyl)stibine}palladium(II)

Tri(2-methylphenyl)stibine reacts with [PdX2(cod)] or PdX2 (X = Cl or Br) to give the trans-[PdX2{Sb(2-Me– C6H4)3}2]. The single crystal X-ray structures of trans-[PdX2{Sb(2-Me-C6H4)3}2] (X = Cl or Br) revealed that the palladium atom is a square planar environment with mutually trans-Sb(2-methylphenyl)3 ligands. Iodine analogous of complex can also be prepared from trans metallation reaction with sodium iodine.
