Supramolecular isomeric flat and wavy honeycomb networks: additive agent effect on the ligand linkages

This is the authors' abstract. We don't add key points for this paper.

Two genuine supramolecular isomers of Cd(II) coordination polymers with an identical formula of [Cd(pptp)(ox)]n (1a and 1b) (pptp = 2-(3-(4-(pyridin-4-yl)phenyl)-1H-1,2,4-triazol-5-yl)pyridine, H2ox = oxalic acid) have been hydrothermally synthesized and characterized. Both compounds possess the rod-like binuclear [Cd2(pptp)2] subunit, which are linked by the ox ligand to afford either a flat or wavy two-dimensional (2D) 63-hcb network, depending upon whether the additive agent is used for the reaction. The photoluminescence behaviour of the compounds was also discussed.
