Abstract:
The reaction of copper(H) bis(N,N-dialkyldithio-carbamates) with copper(H) halides can lead to a variety of complexes containing copper(H) or copper- (II) and copper(I) ions [ 1, 21 . Bis(piperidyldithio-carbamate)copper(II), [Cu(pipdtc)?] reacts with copper(I1) halides leading to a series of compounds containing both copper(H) and copper(I) ions of the form Cu(II) (pipdtc)z(Cu(I)X), (X = Cl, Br, n = 4,6) [l , 21. X-ray crystal structures of the bromide com- plexes for n = 4,6 show them to consist of polymeric sheets of the copper(H) bisdithiocarbamate complex linked through Cu(I)Br chains, each copper(I1) ion being bridged to four copper(I) ions by the dithio- carbamate sulphur atoms [l] , Fig. 1. The analogous chloride complex Cu(II)(pipdtc),(CuC1)4 is iso-structural with the corresponding bromide com-pound.
