Structure and spectroscopic properties of etherates of the beryllium halides
ZEITSCHRIFT FUR NATURFORSCHUNG SECTION B-A JOURNAL OF CHEMICAL SCIENCES(2023)
Abstract
The synthesis of beryllium halide etherates and the solution behavior in benzene, dichloromethane, and chloroform was studied by NMR, IR, and Raman spectroscopy. Mononuclear units of [BeX (2)(L)(2)] (X = Cl, Br, I; L = Et2O, thf) were identified as the favorably formed species in solution. Treatment of the mononuclear diethyl ether beryllium halide adduct with one equivalent beryllium halide formed the dinuclear compounds [BeX (2)(OEt2)](2) (X = Cl, Br, I). The solid-state structures of [BeCl2(thf)(2)] and [BeBr2(thf)(2)] have been determined by single crystal X-ray diffraction analysis. [BeI2(thf)(2)] decomposed in all solvents. In CD2Cl2 the salt [Be(thf)(4)]I-2 was formed, whereas in C6D6 and CDCl3, BeI2 precipitated and [BeI(thf)(3)](+), [Be(thf)(4)](2+) together with the thf ring-opening product [Be(mu(2)-O(CH2)(4)I)I(thf)](2) were observed in solution.
