Synthesis, characterization, and photoluminescence of isostructural Mn, Co, and Zn MOFs having a diamondoid structure with large tetrahedral cages and high thermal stability

Three novel Mn, Co, and Zn MOFs containing large tetrahedral cages have been prepared and are stable up to 400 °C; X-ray diffraction revealed the frameworks are isostructural having a diamondoid structure of "hourglass" subunits connected by triangular carboxylate ligands.
