Linearly bridging CO2 in a metal-organic framework

5 May, 2015 - 14:54

Chem. Commun., 2015, 51,8446-8449
DOI: 10.1039/C5CC01244A, CommunicationFei-Yan Yi, Hai-Long Jiang, Zhong-Ming Sun
A very rare CO2-coordinated metal-organic framework was structurally confirmed by single-crystal X-ray diffraction. The CO2 ligand links two open Zn metal centers in an absolutely linear [small mu ](O,O[prime or minute]) coordination mode with a C[double bond, length as m-dash]O distance of 1.107(4) A. The new complex reported here is stable under ambient conditions and may provide a new strategy for CO2 fixation.
