摘要：

Several new N, N-dialkyldithiocarbamato (R2dtc) complexes of osmium(III) and -(IV) have been synthesized and characterized. An electrochemical study on Os(Et2dtc)3, C10s(Et2dtc)3, and Os2N(Et2dtc)5 has been carried out and the results compared with those of analogous ruthenium and iron complexes. In propylene carbonate solution, Os(dtc)3 exhibits a four-membered electron-transfer series [Os(Et2dtc)3- ⇆ Os(Et2dtc)3 ⇆ Os(Et2dtc)3+ ⇆ Os(Et2dtc)32+] while in acetonitrile solution the redox chemistry is complex with Os(Et2dtc)3 showing a one-electron irreversible oxidation to [(CH3CN)Os(Et2dtc)3]+ in a manner similar to Ru(Et2dtc)3. The 1H NMR properties of the complexes XOs(R2dtc)3 (X=Cl, I, and PPh3), [Os2(R2dtc)5]Cl, and Os(Et2dtc)3 have been determined. © 1979, American Chemical Society. All rights reserved.
