Abstract The attempted synthesis of bis(diphenylphosphinomethyl) phenylarsane and tris(diphenylphosphinomethyl) arsane through condensation of chloro arsanes and diphenyl (trimethylsilylmethyl) phosphane yielded a number of side products originating from migratory and redox-reactions in addition to the targeted ligands. An unexpected, 1,3,4-phosphadiarssolan-1-ium salt was obtained and crystallographically

Treatment of a dichloromethane solution of the salt [N(PPh3)2]2[Ru4(µ-H)2(CO)12] with two equivalents of the complex [M(NCMe)4]PF6(M = Cu or Ag) at –30 °C, followed by the addition of one equivalent of the appropriate bidentate ligand Ph2As(CH2)nEPh2(E = As or P; n= 1 or 2) affords the mixed-metal cluster compounds [M2Ru4(µ3-H)2µ-Ph2As(CH2)nEPh2}(CO)12][M = Cu, E = P, n= 1 (1) or 2 (2); M = Ag, E = P,

The novel mixed-metal cluster compounds [M2Ru4(μ3-Ph2As(CH2)n-PPh2}(CO)12] (M = Cu or Ag; n = 1 or 2) have been synthesized in good yield (ca. 65–70%0. Variable temperature 1H and 31P-1H} NMR spectroscopic studies demonstrate that two distinct structural isomers exist in solution at low temperature for both copper-ruthenium clusters and that each of these pairs of isomer undergoes interconversion
Subvalent mercuryclusters [Hg3(LL)3]4+ with LL=dpam (dpam=Ph2AsCH2AsPh2) or Ph2AsCH2PPh2 and dpam–dppm (dppm=Ph2PCH2PPh2) or dpam–Ph2AsCH2PPh2 mixed ligand complexes were obtained by reaction of [Hg2]2+ with the ligands or by reduction of a mixture of [Hg(Me2SO)6](O3SCF3)2 and the ligands with elemental mercury. Whereas the equilibrium 2Hg2++Hg⇌[Hg3]4+ is far to the right in the presence of the ligands
