The first examples of Co(ii) mesoionic carbene complexes (CoX2DippMIC2; X = Cl-, Br-, I-) demonstrate a new electronic perturbation on tetrahedral Co(ii) complexes. Using absorption spectroscopy and magnetometry, the consequences of the MIC's strong σ-donating/minimal π-accepting nature are analyzed and shown to be further tunable by the nature of the coordinated halide.
首例钴（II）中离子卡宾配合物（CoX2DippMIC2；X = Cl-、Br-、I-）展示了对四面体钴（II）配合物的一种新的电子扰动。利用吸收光谱法和磁强计，分析了中离子卡宾（MIC）强σ供体/最小π受体性质的影响，并表明其可通过配位卤化物的性质进一步调节。
