• Three new coordination polymers based on 5-Aminonicotinic acid with different structures.
• The effects of the reaction solvents, temperatures and metal cations have been discussed.
• The amino groups of 5-Aminonicotinic acid also take part in coordination.
• The solid-state photoluminescence for 1 and 2 were also studied.
Three new coordination polymers (CPs) based on rigid ligand 5-Aminonicotinic acid (5-anaH), [Cd(5-ana)2]·(H2O)2 (1), [Cd(5-ana)(HCOO) ] (2) and [Cu(5-ana)2] (3), have been synthesized under different solvent media and temperatures. All CPs are characterized by single crystal X-ray diffraction, elemental analysis, IR spectroscopy, powder X-ray diffraction and thermogravimetric analysis. Compound 1 is a two-dimensional (2D) (4,4)-connected layered structure contains 1D open channels. 2 shows a 2-nodal (3,5)-connected three-dimensional (3D) framework with {52·6}{53·63·73·8} topology. While 3 displays a 3D (3,6)-connected homochiral framework with {42·6}2{44·62·85·104} topology. The solid-state photoluminescence for 1 and 2 were also studied.

While 3 displays a 3D (3,6)-connected homochiral framework. The significant structural differences between these CPs are related to the reaction solvents, temperatures and metal cations. The solid-state photoluminescence for 1 and 2 were studied.Figure optionsDownload as PowerPoint slide
