Linearly bridging CO2 in a metal–organic framework†
Abstract
A very rare structurally characterized CO2-coordinated metal–organic framework was synthesized by a solvothermal reaction. The CO2 ligand links two open Zn metal centers in a linear and symmetrical μ(O,O′) coordination mode with a CO distance of 1.107(4) Å. The new complex reported here is stable under ambient conditions and may provide a new strategy for CO2 fixation.
