Binding CO₂ by a Cr₈ Metallacrown [PDF]

Angewandte Chemie International Edition, 2017
AbstractThe {Cr8} metallacrown [CrF(O2CtBu)2]8, containing a F‐lined internal cavity, shows high selectivity for CO2 over N2. DFT calculations and absorption studies support the multiple binding of F‐groups to the C‐center of CO2 (C⋅⋅⋅F 3.190(9)–3.389(9) Å), as confirmed by single‐crystal X‐ray diffraction.

Investigating the Structural Factors Influencing the Magnetic Interaction between Individual Copper Spins in the CuCu4 Metallacrown Complex, from Its Bulk Form to Its Adsorption on Au(111)

Advanced Materials Interfaces
Metal‐organic complexes with multiple metal ions and unsaturated spin structures are intriguing for their potential to tune magnetic properties. We focus on the Cu(II)[12‐MCCu(II)N(Shi)‐4] metallacrown complex (CuCu4) to show how phase‐dependent ...
