Linear, Trinuclear Cobalt Complexes with o-Phenylene-bis-Silylamido Ligands.
Transamination of [Co{N(SiMe3)2}2]2with C6H4(NHSiiPr3)2gave the centrosymmetric trinuclear [{CoterN(SiMe3)2(μ-η-[o-C6H4(κNSiiPr3)2])}2Coint] (1) (Coter, Coint=terminal, internal Co, respectively), with 3-coordinate Coter, and Coint"sandwiched" between the o-phenylenes of the two ligands; experimental and computational data support CoIIcentres and ditopic o-amido-imino-cyclohexen-allyl ligands; magnetic studies reveal intermetallic ferromagnetic interactions and single-molecule magnet (SMM) character. One-electron reduction of 1 yielded the salt [K(18-crown-6)(THF)2][{CoterN(SiMe3)2(μ-η-[o-C6H4(κNSiiPr3)2])}2Coint] (4) with the anion isostructural to 1. The centrosymmetric Fe complex [{FeterN(SiMe3)2(μ-η-[o-C6H4(κNSiiPr3)2])}2Feint] (5), analogous to 1, was also obtained.
