Аннотация
Three new chalcogenide vanadium complexes with a β-diketiminate ligand have been synthesized by reduction of the elemental chalcogens (S, Se, Te) with [(µ-η 6 :η 6 -toluene){V(nacnac)} 2 ] (1) (nacnac = HC(C(Me)NC 6 H 3 - i Pr 2 ) 2 ). The structures of the sulfide and selenide complexes [((nacnac)V = E) 2 (μ,ƞ 2 -E 2 )] (E = S (2), Se (3)) are similar; the chalcogenides act both as bridging (E 2 2- ) and terminal (E 2- ) ligands. In compound [V 2 (µ-Te) 2 (nacnac) 2 ] (4), all tellurium atoms are present only as bridging Te 2- ligands. The compounds have been characterized by IR-spectroscopy, elemental analysis, and single-crystal X-ray diffraction. The possibility of the formation of additional V = Te bonds in 4 has been studied using Hirshfeld analysis. It has been found that the difference in the reactivity of 1 towards Te is not due to the steric hindrance.
