SYNTHESIS AND STRUCTURE OF A BINUCLEAR Pd(II) CHLORANILATE COMPLEX

摘要

A binuclear complex of palladium (Et3NH)(2)[Pd-2(ca)(2)(mu-Cl)(2)]center dot 2CH(3)CN is synthesized by ligand-exchange reaction between [PdCl2(PhCN)(2)] and (Et3NH)(2)ca (ca(2-) = chloranilate) taken in a 1:1 molar ratio. Its crystal structure is determined. Chloranilate ca(2-) dianion is coordinated to Pd(II) as C-donor bidentate ligand. Using cyclic voltammetry (CV) of the complex in CH3CN, non-reversible oxidation at E-a = 1.58 V and quasi-reversible reduction with E-b = -0.80 V and E-a = -0.54 V (relative to Ag/AgCl) is found. The electron structure of the complex is examined.
