Supramolecular
coordination compounds (SCCs) represent the power
of coordination chemistry methodologies to self-assemble discrete
architectures with targeted properties. SCCs are generally synthesized
in solution, with isolated fully coordinated metal atoms as structural
nodes, thus severely limited as metal-based catalysts. Metal–organic
frameworks (MOFs) show unique features to act as chemical nanoreactors
for the <i>in situ</i> synthesis and stabilization of otherwise
not accessible functional species. Here, we present the self-assembly
of Pd<sup>II</sup> SCCs within the confined space of a pre-formed
MOF (SCCs@MOF) and its post-assembly metalation to give a Pd<sup>II</sup>–Au<sup>III</sup> supramolecular assembly, crystallography
underpinned. These SCCs@MOFs catalyze the coupling of boronic acids
and/or alkynes, representative multi-site metal-catalyzed reactions
in which traditional SCCs tend to decompose, and retain their structural
integrity as a consequence of the synergetic hybridization between
SCCs and MOFs. These results open new avenues in both the synthesis
of novel SCCs and their use in heterogeneous metal-based supramolecular
catalysis.
