Popis: Four binuclear dmit complexes of palladium(II), having μ-X or -S bridges, have been synthesized and characterized. The complexes, (Bu 4 N)[Pd 2 X 2 (dmit) 2 ] (X=Cl ( 1 ) and Br ( 2 )), were prepared by metathesis reaction from bridged precursors, [(Bu 4 N) 2 (Pd 2 X 6 )]. The complexes, D 2 [Pd 2 (Sph) 2 (dmit) 2 ] (D=Bu 4 N ( 3 ) and Et 4 N ( 4 )), were prepared by cracking reaction of polymeric precursor [Pd 2 Cl 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−).
