1-三(吡唑基)硼酸铍卤化物TpBeX (X = Cl 1, Br 2, I 3, F 4)、TpBeF (5) 和1-三(吡唑基)硼酸铍氢化物、氘化物和叠氮化物TpBeX (X = H 6, (2)H (D) 7, N3 的吡唑加合物的合成和晶体结构8；描述了Tp＝1-三吡唑基硼酸酯。此外，(9)Be-NMR 光谱被引入作为合适的分析工具，用于杂配有机铍卤化物、拟卤化物和氢化物的原位表征。对不同溶剂和溶剂混合物的研究使得仅基于第二取代基的变化就可以制定铍杂配位配合物的化学位移的参考指南。
The synthesis and crystal structures of 1-tris(pyrazolyl)borate beryllium halides TpBeX (X = Cl 1, Br 2, I 3, F 4), the pyrazole adduct of TpBeF (5) and of 1-tris(pyrazolyl)borate beryllium hydride, deuteride and azide TpBeX (X = H 6, (2)H (D) 7, N3 8; Tp = 1-trispyrazolylborate) is described. In addition, (9)Be-NMR spectroscopy is introduced as suitable analytical tool for the in situ characterization of heteroleptic organoberyllium halides, pseudohalides and hydrides. Studies in different solvents and solvent mixtures allowed the formulation of a reference guide for the chemical shift of heteroleptic coordination complexes of beryllium only based on variation of the second substituent.
