The reactivity patterns of low-coordinate iron-hydride complexes.
We report a survey of the reactivity of the first isolable iron-hydride complexes with a coordination number less than 5. The high-spin iron(II) complexes [(beta-diketiminate)Fe(mu-H)] 2 react rapidly with representative cyanide, isocyanide, alkyne, N 2, alkene, diazene, azide, CO 2, carbodiimide, and Brønsted acid containing substrates. The reaction outcomes fall into three categories: (1) add...
متن کاملElectronically unsaturated three-coordinate chloride and methyl complexes of iron, cobalt, and nickel.
Three-coordinate organometallic complexes are rare, especially with the prototypical methyl ligand. Using a hindered, rigid bidentate ligand (L), it is possible to create 12-electron methyliron(II) and 13-electron methylcobalt(II) complexes. These complexes are thermally stable, and (1)H NMR spectra suggest that the low coordination number is maintained in solution. Attempts to create the 14-el...
متن کاملStructural classification of metal complexes with three-coordinate centres.
Attempts to describe the geometry about three-coordinate silver(i) complexes have proven difficult because interatomic angles generally vary wildly and there is no adequate or readily available classification system found in the literature. A search of the Cambridge Structural Database shows that complexes formed between any metal centre and three non-metal donors (18 001 examples) usually adop...
متن کاملFour-coordinate, trigonal pyramidal Pt(II) and Pd(II) complexes.
We report herein the characterization of electrophilic, trigonal bipyramidal {[SiP(3)(R)]Pt(L)}(+) cations ([SiP(3)(R)] = [(2-R(2)PC(6)H(4))(3)Si]; R = Ph, (i)Pr) that feature weakly coordinated ligands including CH(2)Cl(2), Et(2)O, toluene, and H(2). A cationic toluene adduct that shows a close platinum aryl C-H σ-contact is perhaps most noteworthy in this context. For the isopropyl-substitute...
متن کاملActivation and cleavage of dinitrogen by three-coordinate metal complexes involving Mo(III) and Nb(II/III).
Density functional calculations have been employed to rationalize why the heteronuclear N(2)-bridged Mo(III)Nb(III) dimer, [Ar((t)Bu)N](3)Mo(mu-N(2))Nb[N((i)Pr)Ar](3)(Ar = 3,5-C(6)H(3)Me(2)), does not undergo cleavage of the dinitrogen bridge in contrast to the analogous Mo(III)Mo(III) complex which, although having a less activated N-N bond, undergoes spontaneous dinitrogen cleavage at room te...
