Probing the electronic boundaries between trigonal and tetrahedral coordination at beryllium

NEt 3 adducts to BeCl 2 , BeBr 2 and BeI 2 were synthesized and characterised via NMR and IR spectroscopy as well as X-ray diffractometry. Depending on the halide and the state of matter these are either mono- or dinuclear. Population analyses were performed to determine the influence of the metal&#...

Description
Summary:NEt 3 adducts to BeCl 2 , BeBr 2 and BeI 2 were synthesized and characterised via NMR and IR spectroscopy as well as X-ray diffractometry. Depending on the halide and the state of matter these are either mono- or dinuclear. Population analyses were performed to determine the influence of the metal's partial charge on the coordination geometry. Additionally, the reactivity of these compounds towards C-Cl- and O-H-bonds was studied. The influence of the beryllium atom's partial charge on its coordination sphere was investigated experimentally and computationally on NEt 3 adducts to BeCl 2 , BeBr 2 and BrI 2 .
