A self-penetrated chiral cobalt camphorate coordination polymer with antiferromagnetically coupled paddlewheel clusters

Diverse Topologies in Chiral Divalent Metal Camphorate Coordination Polymers Containing 4,4′-Dipyridylamine

“…The resulting 6-connected networks of 4 and 5 have a simple non-interpenetrated 4 12 6 3 pcu primitive cubic topology (Figure b), in contrast to the self-penetrated 4 8 6 6 8 6-connected rob network seen in an analogous phase [Co 2 ( d -cmph) 2 (4,4′-bipyridine)] n where virtually identical [Co 2 ( d -cmph) 2 ] n layers are cross-pillared by rigid rod 4,4′-bipyridine ligands . A related phase containing the even longer rod-like dipyridyl ligand bis­(4-pyridylmethyl)­piperazine (bpmp), [Co 2 ( d -cmph) 2 (bpmp)] n , exhibits a different self-penetrated 4 4 6 10 8 mab 6-connected topology . It is possible that the relatively short length and the kinked disposition of the pyridyl nitrogen donor atoms in the dpa ligands in 4 permit the self-assembly of the non-self-penetrated pcu net in lieu of any 6-connected self-penetrated topology.…”

Two New Cadmium(II) Compounds based on Distinct Second Building Subunits: Solvothermal Syntheses, Crystal Structures, and Luminescent Properties

“…During the past few decades, metal‐organic frameworks (MOFs) have experienced an explosive growth not only because of their charming topological architectures but also owing to their potential applications in luminescence, gas storage and separation, magnetism and catalysis 1–5. However, controllable assembly of MOFs with unique structural features and certain functions remains a fundamental scientific challenge to chemists and material scientists 6,7. Therefore, for the self‐assembly of MOFs, selection of an appropriate organic ligand and synthetic strategies are key factors for achieving expected compounds 8–10.…”
