Abstract

The anionic tantalum complex (I^tBuH)[Ta(NMe₂)₃Cl₃] (I) is synthesized by the reaction of [Ta(NMe₂)₃Cl₂]₂ with N-heterocyclic carbene I^tBu and is isolated as two crystalline modifications (Ia and Ib). Its fluoride analogue (I^tBuH)[Ta(NMe₂)₃F₃] (II) is synthesized by the reaction of Ta(NMe₂)₅ with (I^tBuH)BF₄. The structures of the complexes are determined by X-ray diffraction analysis (CIF files CCDC nos. 1977540 (Ia), 1977541 (Ib), and 1977542 (II)).

摘要

通过[Ta（NMe ₂）₃ Cl ₂ ] ₂与N-杂环卡宾I ^t Bu的反应合成阴离子钽络合物（I ^t BuH）[Ta（NMe ₂）₃ Cl ₃ ]（I），并将其分离出来。作为两个结晶变体（Ia和Ib）。通过Ta（NMe ₂）₅与（I ^t BuH）BF ₄的反应合成其氟化物类似物（I ^t BuH）[Ta（NMe ₂）₃ F ₃ ]（II）。。配合物的结构通过X射线衍射分析确定（CIF文件CCDC号1977540（Ia），1977541（Ib）和1977542（II））。
