| 1 | Triplet bismuthinidenes featuring unprecedented giant and positive zero field splittings显示文摘Isolation of triplet pnictinidenes,which bear two unpaired electrons at the pnictogen centers,has long been a great challenge due to their intrinsic high reactivity.Herein,we report the syntheses and characterizations of two bismuthinidenes MsFluindtBu-Bi(3)and MsFluind*-Bi(4)stabilized by sterically encumbered hydrindacene ligands.They were facilely prepared through reductions of the corresponding dichloride precursors with 2 molar equivalents of potassium graphite.The structural analyses revealed that 3 and 4contain a one-coordinate bismuth atom supported by a Bi-C singleσbond.As a consequence,the remaining two Bi 6p orbitals are nearly degenerate,and 3 and 4 possess triplet ground states.Experimental characterizations with multinuclear magnetic resonance,magne tome try and near infrared spectroscopy coupled to wavefunction based ab initio calculations concurred to evidence that there exist giant and positive zero field splittings(>4300 cm-1)in their S=1 ground states.Hence even at room temperature the systems almost exclusively populate the lowest-energy nonmagnetic Ms=0 level,which renders them seemingly diamagnetic. | Mengyuan Wu Wang Chen Dongmin Wang Yizhen Chen Shengfa Ye Gengwen Tan | 2023 | National Science Review2023，10，10： | 0 |
| 2 | Probing electronic structures of transition metal complexes using electron paramagnetic resonance spectroscopy显示文摘Electron paramagnetic resonance(EPR)or electron spin resonance(ESR)has been widely employed to characterize transition metal complexes.However,because of the high degree of complexity of transition metal EPR spectra,how to extract the underlying electronicstructure information inevitably poses a major challenge to beginners,in particular for systems with S>1/2.In fact,the physical principles of transition metal EPR have long been well-established and since 1970s a series of dedicated voluminous monographs have been published already.Not surprisingly,they are not appropriate stating points for novices to grasp a panorama of the profound theory prior to scrutinizing in-depth references.The present review aims to fill this gap to provide a perspective of transition metal EPR and unveil some peculiar subtleties thereof on the basis of our recent work. | Shengfa Ye | 2023 | Magnetic Resonance Letters2023，3，1： | 0 |
