Binding CO 2 by a Cr 8 Metallacrown

The {Cr 8 } metallacrown [CrF(O 2 C t Bu) 2 ] 8 , containing a F‐lined internal cavity, shows high selectivity for CO 2 over N 2 . DFT calculations and absorption studies support the multiple binding of F‐groups to the C‐center of CO 2 (C⋅⋅⋅F 3.190(9)–3.389(9) Å), as confirmed by single‐crystal X‐ra...

Description
Summary:The {Cr 8 } metallacrown [CrF(O 2 C t Bu) 2 ] 8 , containing a F‐lined internal cavity, shows high selectivity for CO 2 over N 2 . DFT calculations and absorption studies support the multiple binding of F‐groups to the C‐center of CO 2 (C⋅⋅⋅F 3.190(9)–3.389(9) Å), as confirmed by single‐crystal X‐ray diffraction.
