1 Chemistry

The berylliumbromide-acetonitrile complex [BeBr₂(CH₃CN)₂] (1) was prepared in a one-step synthesis from beryllium powder and bromine in acetonitrile at room temperature to give colourless single crystals, which were characterized by X-ray diffraction and IR spectroscopy. Compound 1 crystallizes orthorhombically in the space group Pnma with four formular units per unit cell. Lattice dimensions at 100(2) K: a = 1253.1(1), b = 1003.7(1), c = 650.8(1) pm, R₁ = 0.0217. The structure of 1 consists of monomeric molecules with site symmetry m and distances Be-Br of 214.7(5) pm and Be-N of 171.3(4) pm.
