在N，N-二异丙基乙胺（DIPEA）存在下，TpBeCl {Tp =三吡唑硼酸盐[HB（C3 N2 H3）3]-}与H2O和D2 O的水解反应定量生成三聚氢氧化铍蝎形酸盐配合物[Be 3（μ-OX）3（Tp）3]（X = H：1，D：2）。根据单晶X射线衍射研究和理论计算，该配合物含有六元Be 3 O3环。依赖于温度的1H和9 Be NMR光谱确定1在溶液中具有动态结构。此外，还报道了由BeBr 2的四氢呋喃和二氯甲烷溶液水解得到的[Be 3（µ-OH）3（Br）3（thf）6]的结构。
The controlled hydrolysis of TpBeCl {Tp = trispyrazolylborate [HB(C3N2H3)3]–} with H2O and D2O in the presence of N,N-diisopropylethylamine (DIPEA) yields the trimeric beryllium hydroxide scorpionate complexes [Be3(µ-OX)3(Tp)3] (X = H: 1, D: 2) quantitatively. The complexes contain six-membered Be3O3 rings according to single-crystal X-ray diffraction studies and theoretical calculations. Temperature-dependent 1H and 9Be NMR spectroscopy established that 1 has a dynamic structure in solution. In addition, the structure of [Be3(µ-OH)3(Br)3(thf)6], which was obtained from hydrolysis of a solution of BeBr2 in tetrahydrofuran and CHCl3, is reported.
