Tetraruthenium carbonyl complexes containing germyl and stannyl ligands from the reactions of Ru4(CO)13(μ-H)2 with HGePh3 and HSnPh3

摘要: Abstract The compounds Ru4(CO)12(GePh3)2(μ-H)4, 1 and Ru4(CO)12(SnPh3)2(μ-H)4, 2 were obtained from the reactions of Ru4(CO)13(μ-H)2 with HGePh3 HSnPh3, respectively. Both contain a nearly planar butterfly structure for four metal atoms two GePh3/SnPh3 ligands bridging hydride around periphery cluster. When heated, converted into complexes Ru4(CO)12(μ4-EPh)2, 3, E = Ge, 4, E = Sn, by cleavage phenyl groups each GePh3 ligands.
