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.
