摘要: Abstract The first examples of bridging tin- and germanium-substituted metallocarboxylate ligands have been obtained from the reactions Ph3SnOH Ph3GeOH with Os3(CO)12 under basic conditions. Two products: Os3(CO)10(μ-η2-O=COSnPh3)(μ-OMe), 1 (18% yield) Os3(CO)10(μ-OMe)(μ-OH), 2 (6.9% were reaction in presence [Bu4N]OH methanol solvent. compound Os3(CO)10(μ-η2-O=COGePh3)(μ-OMe), 3 (7.3% was prepared similarly by using place Ph3SnOH. Each products 1–3 characterized structurally single-crystal X-ray diffraction analysis. Compounds each contain an μ-η2-O=COMPh3, M = Sn or Ge ligand a pair osmium atoms triosmium carbonyl cluster complex.
