Abstract
AbstractBeryllium dichloride reacts in dichloromethane suspension with 18‐crown‐6 to give the molecular centrosymmetric complex [(BeCl2)2(18‐crown‐6)] (1), which was characterized by single‐crystal X‐ray diffraction, by vibrational spectroscopy (IR, Raman), and by DFT calculations. 1 crystallizes monoclinically in the space group P21/n with Z = 2. Lattice dimensions at 100(2) K: a = 747.5(1), b = 1373.9(1), c = 899.1(1) pm, β = 94.84(1)°, R1 = 0.0233., Exposition of 1 to moist atmosphere leads to single crystals of [{Be3(μ‐OH)3(H2O)6}(18‐crown‐6)]Cl3·3H2O (2·3H2O), which are characterized by X‐ray diffraction. 2 crystallizes in the triclinic space group P$\rm P\bar1$ with Z = 2. Lattice dimensions at 100(2) K: a = 1046.04(9), b = 1236.12(11), c = 1275.72(13) pm, α = 80.233(8)°, β = 66.439(7)°, γ = 80.053(7)°, R1 = 0.0476.
