Organic heterocycle-affecting the structural variability of Cd(II)-btc coordination polymers (H3btc = benzene-1,3,5-tricarboxylic acid)

Three Cd(II)-btc coordination polymers exhibiting different networks which are affected by co-ligands such as Acridine (L1), Phenanthridine (L2) and Quinoline (L3): 2-D (4,4) net for [Cd(Hbtc)2(HL1)2] (1), 2-D double-layer for [Cd3(btc)2(L2)2(H2O)2].2H2O (2) and 3-D net for [Cd(btc)(HL3).H2O].2H2O (3).

Cd(II)-btc coordination polymers (H3btc = benzene-1,3,5-tricarboxylic acid) containing different heterocyclic aromatic co-ligands have been isolated under hydrothermal conditions. Each polymer shows different network because the co-ligand might serves as the structure-directing template.Figure optionsDownload as PowerPoint slideResearch highlights
► Three new cadmium coordination polymers based on benzene-1,3,5-tricarboxylic acid.
► Different networks are affected by heterocyclic aromatic co-ligands.
► One polymer is a 2-D (4,4) net.
► One polymer is a 2-D double-layer.
► The third one is a 3-D net.
