New organometallic dialkylamido complexes. X-ray crystal structure of Ph2VN(CH2CH2NEt2)2

Open-Shell Organometallics as a Bridge between Werner-Type and Low-Valent Organometallic Complexes. The Effect of the Spin State on the Stability, Reactivity, and Structure

“…Five-coordinate complexes of V(III) are more common than 6-coordinate analogues. Well characterized examples are V(Mes)[CyNC(Mes)NCy] 2 , V(acacen)X (acacen = N,N‘-ethylenebis(acetylacetone iminate; X = Ph, Mes), and V(tmtaa)X (tmtaa = dibenzotetramethyltetraaza[14]annulene; X = Me, Bz, Ph, Mes), , all of type LXXIII , and [N(CH 2 CH 2 Y) 2 ]VX 2 (Y = NEt 2 , PEt 2 , PMe 2 ; X = Me, Ph) ,, of type LXXIV . VXCl 2 ·2THF (X = 2,4-Me 2 C 6 H 4 , Mes, C 6 Me 5 ) compounds are also described, although structural details are not given .…”
