proximity to a halide anion. The study was extended to a structurally related class of 1,3,2-benzodioxastibole derivatives to elucidate their potential for binding halide ions. Multiple geometric conformations were evaluated and various ratios of halide anions were considered. According to the computation results, this class of anion receptors shows strong affinities toward charge-dense halides. These 1
密度泛函理论计算用于设计利用锑(III)二级键相互作用的阴离子受体。对化学文献中发现的有前途的基序进行了计算,在该基序中,两个锑位点非常靠近卤化物阴离子。这项研究扩展到与结构相关的1,3,2-苯并二恶唑烷衍生物类,以阐明其结合卤离子的潜力。评价了多种几何构型,并考虑了各种比例的卤化物阴离子。根据计算结果,这类阴离子受体对电荷密集的卤化物表现出很强的亲和力。制备这些1,3,2-苯并二恶唑烷衍生物以评估其合成可及性。一种物种的结构表征揭示了通过次级键相互作用最多可结合三个电子供体的能力。这开启了这些锑系统用于阴离子结合和识别的未来实验研究。
