Extended-chain, multinuclear transition metal complexes bridged by cyanodiazenido(1-), [N=N-C[triple bond, length as m-dash]N]-, ligands.


PMID 17680044

Abstract

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