“…The overall composition was confirmed by electrospray mass spectrometry (molecular ion at m / z 1079) and elemental analysis to be the expected complex [Ru(CHCHC 6 H 4 Me‐4)(κ 2 ‐S 2 C ⋅ ICy)(CO)(PPh 3 ) 2 ][PF 6 ] ( 2 ). The formulation of this product was in accordance with the reaction of other dithio ligands, such as dithiocarbamates,11a, 15 xanthates16 and dithiophosphinates,17 with vinyl precursors such as 1 .…”

Not so innocent: Sterically tuneable dithiocarboxylate ligands derived from N‐heterocyclic carbenes act as excellent bidentate chelates for ruthenium(II) σ‐alkenyl complexes. However, the most sterically demanding member of the ligand family causes a fascinating and unexpected rearrangement to occur (see figure; ICy=1,3‐dicylohexylimidazolium, IDip=1,3‐bis(2,6‐diisopropylphenyl)imidazolium).

“…This is a field in which we have successfully employed bifunctional dithiocarbamate ligands 5 and, more recently, spacers with both carboxylate and xanthate functionality. 6 (K 2 L 1 ), has already been reported, offering the same number of bonds (9) between the linked metals as the piperazine-derived, [S 2 CNC 4 H 8 NCS 2 ] 2-. K 2 L 1 has been investigated mainly in terms of the ligand itself 7 rather than its complexation behaviour.…”

The ligands KS(2)CN(Bz)CH(2)CH(2)N(Bz)CS(2)K (K(2)L(1)), N(CH(2)CH(2)N(Me)CS(2)Na)(3) (Na(3)L(2)), and the new chelates {(CH(2)CH(2))NCS(2)Na}(3) (Na(3)L(3)) and {CH(2)CH(2)N(CS(2)Na)CH(2)CH(2)CH(2)NCS(2)Na}(2) (Na(4)L(4)), react with the gold(I) complexes [ClAu(PR(3))] (R = Me, Ph, Cy) and [ClAu(IDip)] to yield di-, tri-and tetragold compounds. Larger metal units can also be coordinated by the longer, flexible linker, K(2)L(1). Thus two equivalents of cis-[PtCl(2)(PEt(3))(2)] react with K(2)L(1) in the presence of NH(4)PF(6) to yield the bimetallic complex [L(1){Pt(PEt(3))(2)}(2)](PF(6))(2). The compounds [NiCl(2)(dppp)] and [MCl(2)(dppf)] (M = Ni, Pd, Pt; dppp = 1,3-bis(diphenylphosphino)propane, dppf = 1,1'-bis(diphenylphosphino)ferrocene) also yield the dications, [L(1){Ni(dppp)}(2)](2+) and [L(1){Ni(dppf)}(2)](2+) in an analogous fashion. In the same manner, reaction between [(L'(2))(AuCl)(2)] (L'(2) = dppm, dppf; dppm = bis(diphenylphosphino)methane) and KS(2)CN(Bz)CH(2)CH(2)N(Bz)CS(2)K yield [L(1){Au(2)(L'(2))}(2)]. The molecular structures of [L(1){M(dppf)}(2)](PF(6))(2) (M = Ni, Pd) and [L(1){Au(PR(3))}(2)] (R = Me, Ph) are reported.

“…In recent years, our investigations have concentrated on the additional functionality afforded to metal complexes and gold nanoparticles by the addition of dithiocarbamate [17] and xanthate [18] ligands. In particular, their application in the formation of multimetallic assemblies is noteworthy [19].…”

2 = CO2Me) provide a versatile entry point for many subsequent transformations, such as their reaction with carbon disulfide to provide zwitterionic dithiocarboxylate products. These compounds react with the coordinativelyunsaturated ruthenium vinyl precursors [Ru(CH=CHR 3)Cl(CO)(PPh3)2] (R 3 = C6H4Me-4, 1-Pyrenyl) to yield heterotrimetallic Fe2Ru compounds, exhibiting vinyl moieties at both iron and ruthenium centres. The emission associated with the pyrenyl unit is enhanced in the diiron vinyliminium ruthenium pyrenyl complex compared to the diethyldithiocarbamate analogue.
