Abstract

The preparations of some new classes of beryllium compounds that have a coordination number of 3 at beryllium are reported. They were synthesized by the reaction of BeCl2(OEt2)2 with the appropriate lithium salt to give the products [BeMes2(OEt2)] (1; Mes = 2,4,6-Me3C6H2), [Be(OMes*)2(OEt2)] (2; Mes* = 2,4,6-t-Bu3C6H2), and [Be(SMes*)2(THF)]·PhMe (3). The compounds were characterized by 1H NMR and IR spectroscopy, C and H analysis, and X-ray crystallography. The crystal structure of [BeCl2(OEt2)2] (4) was also determined. Crystal data (Mo Kα (λ = 0.710 69 Å) at 130 K) are as follows: [BeMes2(OEt2)] (1), a = 11.913(3) Å, c = 28.390(8) Å, V = 4029(2) Å3, tetragonal, space group [formula omitted], 975 (I > 3σ(I)) data, R = 0.042; [Be(OMes*)2OEt2] (2), a = 25.022(9) Å, b = 9.834(3) Å, c = 16.290(4) Å, β = 96.48(3)°, V = 3982(2) Å3, monoclinic, space group C2/c, 3173 (I > 3σ(I)) data, R = 0.051; [Be(SMes*)2THF]·PhMe (3), a = 8.695(4) Å, b = 17.399(10) Å, c = 17.437(8) Å, α = 60.80(4)°, β = 83.29(4)°, γ = 84.24(4)°, V = 2284(2) Å3, triclinic, space group [formula omitted], 3751 (I > 2σ(I)) data, R = 0.061; [BeCl2(OEt2)2] (4), a = 7.486(3) Å, c = 20.022(8) Å, V = 971.7(6) Å3, trigonal, space group P3121, 646 (I > 2σ(I)) data, R = 0.028.
