Non-interpenetrating honeycomb-like 2D [6,3] network built by a novel trigonal metalloligand

Abstract

The combination of a novel trigonal metalloligand and linear linker affords the large non-interpenetrating honeycomb-like 2D [6,3] network in spite of the large hexagon lattice dimension.

“…The role of bridging ligands in the formation of structurally interesting metal-organic frameworks (MOFs) is of significant importance for the design of multi-functional MOFs and coordination polymers (Li & Zhou, 2009;Huh et al, 2010;Huh et al, 2009;Youm et al, 2004). For instance, the reaction between a Zn(II) ion and a new C 2 h -symmetric bridging ligand, 3,3"-dicarboxy-1,1′:4′,1"-terphenyl (DCT), in the presence of 1,4-diazacyclo[2,2,2]octane (DABCO) afforded a new nanoporous Zn-MOF containing DABCO ligands with an uncoordinated nitrogen atom towards onedimensional channels.…”

“…To the best of our knowledge, only a few types of metalloligands have been so far been reported (i.e., linear, [3,5] trigonal, [4,6] and squareplanar [7] ) despite their great potential for fabricating specific topologies. We have focused on synthesizing novel metalloligands and their subsequent incorporation into new functional coordination polymers.…”

“…[3,4] The metalloligand should have a second coordination sphere comprised of exooriented donor atoms and endo-oriented donor atoms that complete the first coordination sphere of an unsaturated transition-metal moiety. [4] The geometric orientation of the second coordination sphere of the metalloligand depends on the preferred geometry of the metal ions and the nature of the ligands bearing the multifunctional groups.…”

“…We have focused on synthesizing novel metalloligands and their subsequent incorporation into new functional coordination polymers. 4 ] 3 ·x S (2·x S) was characterized by single-crystal X-ray structure analysis (L = hydrotris(1,2,4-triazolyl)borate anion, S = solvent).
