An unprecedented CoII cuboctahedron as the secondary building unit in a Co-based metal–organic framework

Author affiliations

Abstract

A cubic metal–organic framework with an unprecedented octanuclear secondary building unit (SBU) was isolated. The obtained SBU is composed of 8 CoII ions at each vertex, 6 μ4-OH groups at each face, and 12 cpt ligands framing the metal core. The cuboctahedra arrange in a ubt framework topology, eliciting a highly symmetrical MOF structure. Magnetic measurements as well as DFT calculations on this crystalline MOF reveal intramolecular antiferromagnetic coupling between CoII ions in the octanuclear SBU.
