in the construction of porous metal−organic frameworks (MOFs).
A solvothermal reaction of TCBPB and a zinc salt in the presence
of pyridine produces 1, an unstable MOF consisting of a tetrazinc
secondary building unit (SBU) with labile terminal ligands. Changing
pyridine to a noncoordinating base in the assembly procedure
affords 2, a stable MOF with permanent porosity containing an
octazinc SBU without labile terminal ligands.
