Unique Coordination-Based Heterometallic Approach for the Stoichiometric Inclusion of High-Valent Metal Ions in a Porous Metal–Organic Framework

A heterometallic metal–organic framework incorporating Zn2+ and Ti4+ is successfully synthesized. The unique coordination mode of each metal ion to 2-oxido-1,4-benzenedicarboxylate leads to Zn6Ti2 building blocks, which extend to form a double-walled primitive cubic net. This material possesses a permanent porosity and long-term stability.
