Abstract
A series of low-coordinate, high-spin,
mono- and dinuclear cobalt(I) complexes bearing an extremely bulky
amide (L″ = N(Ar*)(SiPh<sub>3</sub>); Ar* = C<sub>6</sub>H<sub>2</sub>{C(H)Ph<sub>2</sub>}<sub>2</sub>Me-2,6,4) ligand have been
synthesized and characterized. These include the first example of
a neutral two-coordinate cobalt(I) complex, [L″Co(IPriMe)]
(IPriMe = :C{N(Pr<sup><i>i</i></sup>)C(Me)}<sub>2</sub>),
which has a near-linear cobalt coordination geometry
