Strategies, linkers and coordination polymers for high-performance sorbents
A linking ligand compound includes three bidentate chemical moieties distributed about a central chemical moiety. Another linking ligand compound includes a bidentate linking ligand and a monodentate chemical moiety. Coordination polymers include a plurality of metal clusters linked together by residues of the linking ligand compounds.

wherein:
R 1 and R 1 ′ are each independently CO 2 R 2 , CONR 2 2 , and CN; and
R 2 is H or a metal cation.
2. A metal cluster comprising metal ions selected from the group consisting of Group 1 through 16 metals of the IUPAC Periodic Table of the Elements including actinides, lanthanides, and combinations thereof and a residue of a compound having formula IX:
