Summary: Magnetically active atomic distances can directly or indirectly impact the magnetic ordering in a given system. We synthesized three novel quasi-one-dimensional organic-inorganic hybrid cobalt chloride chain compounds and characterized their magnetic and thermodynamic properties. These compounds exhibit anti-ferromagnetic intrachain coupling and the strength of correlations is comparable across the three materials. The interchain Co-Co distance, which is determined by the size of the organic cation, is directly related to the temperature of long-range magnetic ordering.

Summary: Potential-dependent selectivity changes are widely observed in electrocatalysis, but a detailed understanding of these changes at an atomic level is still lacking. In this study, we use a model atomically dispersed nickel catalyst to obtain a comprehensive view of potential-induced structure changes during the CO2 reduction reaction. Our findings show that the catalyst exhibits volcano-like selectivity changes that are dependent on the distance between the nickel atom and the carbon basal plane. Theoretical calculations suggest that local dynamic behaviors play a crucial role in regulating the distribution of the d band center of nickel.
