Constructing chiral MOFs by functionalizing 4,2′:6′,4′′-terpyridine with long-chain alkoxy domains: rare examples of neb nets

Abstract

Reactions of 4′-(4-ⁿalkyloxyphenyl)-4,2′:6′,4′′-terpyridines (alkyl = hexyl or nonyl) with Co(NCS)₂ lead to three structurally characterized chiral 3D assemblies which adopt rare neb topologies. For the ⁿhexyl-functionalized ligands, both enantiomorphic lattices of the neb nets (crystallizing in the tetragonal space groups P4₁2₁2 and P4₃2₁2, respectively) are presented.
