Abstract :

Keywords: Coordination; Difluorodithiophosphate; Lability; Ruthenium(II); Structure Abstract An improved synthetic route of [N.sup.nPr.sub.4][S.sub.2PF.sub.2] was devised, and its structure was determined. This unusual dithiophosphate is a good ligand for low valent metal centers and examples of this being hydrolytically stable ruthenium complexes RuH(CO)(S.sub.2PF.sub.2)(PPh.sub.3).sub.2, RuCl(CO)(S.sub.2PF.sub.2)(PPh.sub.3).sub.2 and Ru(S.sub.2PF.sub.2).sub.2(PPh.sub.3).sub.2. Taken together these results give an insight into the bonding of the S.sub.2PF.sub.2 anion to low oxidation state complexes. A comparison of the structural features and reactivity of the complexes with other known Ru(II) complexes is presented. Ru(S.sub.2PF.sub.2).sub.2(PPh.sub.3).sub.2 was successfully carbonylated to give a complex with monohapto and dihapto S.sub.2PF.sub.2 ligands, Ru(CO)(η.sup.1-S.sub.2PF.sub.2)(η.sup.2-S.sub.2PF.sub.2)(PPh.sub.3).sub.2 confirming the lability of the fluorothiophosphate anion. Isomers of this latter complex have been structurally characterized with cis and trans PPh.sub.3.
