The reaction of dichlorido(cod)palladium(II) (cod = 1,5-cyclooctadiene) with 2-(benzylsulfanyl)aniline followed by heating in N,N-dimethylformamide (DMF) produces the linear trinuclear Pd-3 complex bis(mu(2)-1,3-benzothiazole-2-thiolato)bis[mu(2)-2-(benzylsulfanyl)anilinido]dichloridotripalladium(II) N,N-dimethylformamide disolvate, [Pd-3(C7H4NS2)(2)(C13H12NS)(2)Cl-2]center dot 2C(3)H(7)NO. The molecule has (1) over bar symmetry and a Pd center dot center dot center dot Pd separation of 3.2012 (4) angstrom. The outer Pd II atoms have a square-planar geometry formed by an N,S-chelating 2-(benzylsulfanyl)anilinide ligand, a chloride ligand and the thiolate S atom of a bridging 1,3-benzothiazole-2-thiolate ligand, while the central Pd-II core shows an all N-coordinated square-planar geometry. The geometry is perfectly planar within the PdN4 core and the N-Pd-N bond angles differ significantly [84.72 (15)degrees for the N atoms of ligands coordinated to the same outer Pd atom and 95.28 (15)degrees for the N atoms of ligands coordinated to different outer Pd atoms]. This trinuclear Pd-3 complex is the first example of one in which 1,3-benzothiazole-2-thiolate ligands are only N-coordinated to one Pd centre. The 1,3-benzothiazole-2-thiolate ligands were formed in situ from 2-(benzylsulfanyl)aniline.
