AbstractA MHC6 complex of a platinum group metal with a capped octahedral arrangement of donor atoms around the metal center has been characterized. This osmium compound OsH{κ2-C,C-(PhBIm-C6H4)}3, which reacts with HBF4 to afford the 14 e− species [Os{κ2-C,C-(PhBIm-C6H4)}(Ph2BIm)2]BF4 stabilized by two agostic interactions, has been obtained by reaction of OsH6(PiPr3)2 with N,N′-diphenylbenzimidazolium chloride ([Ph2BImH]Cl) in the presence of NEt3. Its formation takes place through the C,C,C-pincer compound OsH2{κ3-C,C,C-(C6H4-BIm-C6H4)}(PiPr3)2, the dihydrogen derivative OsCl{κ2-C,C-(PhBIm-C6H4)}(η2-H2)(PiPr3)2, and the five-coordinate osmium(II) species OsCl{κ2-C,C-(PhBIm-C6H4)}(PiPr3)2.
