Abstract

Kinetic state networks can be trapped by multi-interactive ligands via weak intermolecular interactions. Self-assembly of a tripyridyl multi-interactive ligand K⁺TPHAP⁻ (potassium 2,5,8-tri(4′-pyridyl)-1,3,4,6,7,9-hexaazaphenalene) and ZnI₂ produced seven types of networks depending on the solvent systems (MeOH/additive solvent): [ZnI(TPHAP)]·3.5CH₃OH (1) (from MeOH/DMA), [ZnCl_0.5I_0.5(TPHAP)H₂O]·7H₂O (2) (from MeOH/DMA + water), [ZnI(TPHAP)]·3PhOH·2CH₃OH (3) (from MeOH/phenol (< 33%)), [ZnI(TPHAP)]·5PhOH·2.5CH₃OH (4) (from MeOH/phenol (>50%)), [ZnI(TPHAP)]·2PhNO₂·6CH₃OH (from MeOH/nitrobenzene) (5), [ZnI(TPHAP)CH₃OH]·3PhNH₂ (6) (from MeOH/aniline), and [(ZnI)₂(TPHAP)(HCON(CH₃)₂)₃(CH₃OH)₂]⁺[(ZnI₂)₂(TPHAP)(HCON(CH₃)₂)]⁻ (HCON(CH₃)₂)·4CH₃OH (7) (from MeOH/DMF). All structures were characterized by single crystal X-ray structure determination. Each topology was analyzed by TOPOS. The structures were categorized into two- or three-periodic structure. The structural features of each network were explained by the weak intermolecular interactions between TPHAP⁻ and guest molecules. We demonstrated the multi-interactivity of TPHAP⁻ which can recognize slight differences of the weak intermolecular interactions.
