there is also a minority group of compounds which show either ligand field crossover from high-spin to low-spin configuration or intermediate spin states, and in addition there are some
A good correlation between electronic configuration and structural and chemical bonding factors makes possible the stabilization of unusual oxidation states of transition elements. Such a predictive approach is illustrated by the synthesis and characterization of the first six-coordinated high-spin iron(IV)...
A single-crystal-to-single-crystal transition through irradiation was demonstrated. The changes in structure and electronic configuration as a result of the spin transition are believed to occur concurrently. 展开 关键词: iron LIESST (light‐induced excited spin‐state trapping) magnetic properties ...
Structure and electronic configuration of an iron(II) complex in a LIESST state: a pump and probe method.: Two polymorphs of mononuclear six-coordinate iron(II)
This study introduces a family of multiple charge-density-wave orders in 2D III2–VI3materials, including the chiral Star-of-David configuration. The charge-density-wave transitions involve both metal-to-insulator and insulator-to-insulator transitions, providing a platform for understanding th...
Ab initio calculations have been performed on several ultrathin Fe/Cr/Fe trilayer systems in ferromagnetic configuration, with a fixed width of the spacer chromium slab of three atomic monolayers, and both iron slabs symmetrically varying in a range from 1 to 6 atomic monolayers. We have ...
The experimental results obtained by 0953-8984/9/7/023/img10 conversion electron Mössbauer spectroscopy on the electronic configuration of Fe in 0953-8984/9/7/023/img11 are discussed in the light of ab initio full-potential linear muffin-tin orbital calculations of the isomer shift 0953-8984...

introducing Ru single-atom can modulate electronic structure of metal center in the MOF, leading to the optimization of binding strength for H2O and H*, and the enhancement of HER performance. This work establishes single-atom strategy as an efficient approach to modulate electronic structure of MO...
