Four different three-dimensional metal-fullerene frameworks were synthesized through polymerization of two C60-derived dodecaacids with varying alkyl spacers in the presence of Ca2+, Cu2+ or Cd2+ ions. Structural analysis of the frameworks was performed by single-crystal X-ray diffraction and porosity of the materials was investigated by sorption measurements. [ABSTRACT FROM AUTHOR]

Hexakis-substituted [60]fullerene adducts with icosahedral symmetry provide an unprecedented scaffold for the spatial arrangement of twelve functional groups with high geometric precision. This unique molecular symmetry identifies such polyfunctional organic building blocks as potential highly connective linkers for coordination polymer and metal-organic framework synthesis. Hereby, the linker exhibits a higher connectivity than the metal ions and with the main connectivity based on the ligand, this can create a new type of inversely cross-linked framework. Two hexakis adducts bearing either twelve glycolic acid or 3-hydroxypropionic acid side chains attached to its malonate units were incorporated as organic connectivity centers in the first fullerene-containing three-dimensional frameworks by coordination with Zn2+.

Bridging the gap between fullerenes and MOFs: Against the background of the Golden Gate Bridge, various metal‐organic coordination motifs illustrate the great potential of highly functionalized [60]fullerene derivatives as organic connectivity centers in metal‐organic frameworks. In their Communication on page 15864 ff., Beuerle et al. report on the synthesis and crystallographic analysis of four new metal‐fullerene frameworks cross‐linked by Cu2+, Ca2+, or Cd2+ clusters that feature chiral pores or extended hydrogen‐bonding networks throughout the crystals.
