Abstract: | New cluster complexes W3S4(Acac)3(PPh3)3]PF6 · 0.5CHCl3 (Acac = CH3C(O)CHC(O)CH3) (I) and W3S4(Hfac)3(PPh3)2Br] · 2CHCl3 (Hfac = CF3C(O)CHC(O)CF3) (II) were synthesized. Their molecular and crystal structures were determined by X-ray diffraction. The cis-cis type of coordination of acetylacetonate and hexafluoroacetylacetonate ligands in I and II, respectively, was established, and the PPh3 ligands were found in the trans-positions with respect to the “capping” sulfide ligand (μ3-S). |
