Main Results:

Related Experiment Videos

  • The crystal structure reveals a pyramidal Co(3)O unit formed by bridging hydroxy groups.
  • These units assemble into a honeycomb layer motif through cobalt-oxygen linkages.
  • Phthalate dianions bridge three cobalt atoms, resulting in six-coordinate cobalt centers.

Conclusions:

  • The study provides detailed structural insights into a novel cobalt-phthalate coordination polymer.
  • The observed honeycomb layer structure is attributed to the specific coordination preferences of cobalt and the bridging capabilities of the ligands.
