Halogen- and sulfur-bridged binuclear palladium complexes of 1,3-dithiole-2-thione-4,5-dithiolate, a new exploring in synthetic methods

Four binuclear dmit complexes of palladium(II), having μ-X or -S bridges, have been synthesized and characterized. The complexes, (Bu 4N)[Pd 2X 2(dmit) 2] (X=Cl ( 1) and Br ( 2)), were prepared by metathesis reaction from bridged precursors, [(Bu 4N) 2(Pd 2X 6)]. The complexes, D 2[Pd 2(Sph) 2(dmit)...

Description
Summary:Four binuclear dmit complexes of palladium(II), having μ-X or -S bridges, have been synthesized and characterized. The complexes, (Bu 4N)[Pd 2X 2(dmit) 2] (X=Cl ( 1) and Br ( 2)), were prepared by metathesis reaction from bridged precursors, [(Bu 4N) 2(Pd 2X 6)]. The complexes, D 2[Pd 2(Sph) 2(dmit) 2] (D=Bu 4N ( 3) and Et 4N ( 4)), were prepared by cracking reaction of polymeric precursor [Pd 2Cl 2(Sph) 2] n . The benzenthiolate-bridged anions of 3 and 4 exhibit dinegative ionic charge (2−), which can be deduced from the precursor. On the other hand, the halogen-bridged anions of 1 and 2 are oxidized during the synthetic reaction and show uninegative ionic charge (1−).
