Ideal trigonal prismatic coordination geometry of Co() in a honeycomb MOF with a triptycene-based ligand

A metal-organic framework (MOF) comprised of cobalt ions and triptycene-based 3-fold symmetric bridging ligands 9,10-[1,2]benzenoanthracene-2,3,6,7,14,15(9 H ,10 H )-hexaone ( o -TT) was prepared. Single-crystal structure analysis revealed a 2D honeycomb network structure and the ideal trigonal pris...

Description
Summary:A metal-organic framework (MOF) comprised of cobalt ions and triptycene-based 3-fold symmetric bridging ligands 9,10-[1,2]benzenoanthracene-2,3,6,7,14,15(9 H ,10 H )-hexaone ( o -TT) was prepared. Single-crystal structure analysis revealed a 2D honeycomb network structure and the ideal trigonal prismatic geometry of the Co( ii ) ion. The magnetic anisotropy of the Co( ii ) ion in the trigonal prism coordination geometry was analyzed via magnetic measurements and model calculations. An ideal trigonal prismatic coordination geometry was achieved in the honeycomb metal-organic framework comprised of Co ions and triptycene-based bridging ligands.
