Two distinct coordination polymers [Zn(TBTA)(DMF)2(CH3OH)2]n (1) and {[Zn(TBTA)0.5(DMF)(OH)]-(H2O)}n (2) have been prepared from the vapor diffusion reactions of ZnII nitrate with a rigid ligand tetrabromoterephthalic acid (H2TBTA) under different solvent atmospheres. Both complexes have been characterized by elemental analysis, IR, powder X-ray diffraction, and TG-DTA techniques. Single crystal-X-ray diffraction studies reveal that 1 displays a 1-D linear motif with TBTA spacers whereas 2 presents a 2-D kgm network with the aid of hydroxyl spacers and 4-connected TBTA linkers.
Reactions of ZnII nitrate with a rigid ligand tetrabromoterephthalic acid (H2TBTA) under different solvents afford a 1-D chain complex and a 2-D coordination framework with kgm network topology, which reveals the critical role of solvents on tuning the network structures of coordination polymers.Figure optionsDownload as PowerPoint slide
