Abstract/Summary

Extended-chain complexes containing multiple transition metal centres linked by conjugated mu-cyanodiazenido(1-) ligands [N= N-C N]-have been obtained by reaction of trans-[BrW(dppe)(2)(N2CN)], 1, [dppe = 1,2-bis(diphenylphosphino) ethane] with dirhodium(II) tetra-acetate, bis(benzonitrile) palladium(II) dichloride, and bis(aqua) M(II) bis(hexa. uoroacetylacetonate) (M = Mn, Ni, Cu, Zn): stronger Lewis acids such as tetrakis(acetonitrile) palladium(II) tetra. uoroborate and boron trifl. uoride promote hydrolysis of complex 1, leading to the isolation of a novel carbamoylhydrazido(2-) complex, trans-[BrW(dppe) 2(N2HC=ONH2)](+)[BF4](-).
