In or out? Adaptive metal binding by a diphosphine-based Zr metal-organic cage

Key Points

• Investigate the adaptive metal binding properties of a diphosphine-based zirconium metal-organic cage.
• Synthesis of a lantern-type zirconium metal-organic cage using ditopic carboxylate linkers
• Characterization using single-crystal X-ray diffraction
• Successful synthesis of the metal-organic cage Zr-P2N2
• Demonstration of adaptive metal binding through diphosphine groups
