THERE is at present intense interest in the co-ordination of sulphur to metal ions, especially those of the d-transition series1. Many of these complexes have unusual physical, chemical and structural properties. Little is known, however, about the co-ordination of sulphur to the actinide metal ions, and we report here preliminary observations on the first uranium (IV) complex with a sulphur chelate. The ligand, N,N-diethyldithiocarbamate (dtc), has itself been widely used in the earlier transition metals (many of the known complexes are listed in ref. 2) in which, for example, the apparently simple complexes M (dtc)2 (M (II) = chromium, manganese, iron, copper and zinc) actually involve 5-co-ordination3.
