Abstract
•Three new diverse structural metal–organic coordination polymers are synthesized and characterized.•The ligand used here is flexible.•We study how are the structures affected by cations.
Three new diverse structural metal–organic coordination polymers, [Pb(anti-btx)(H2O) (NO3)2] (1), [Cd(anti-btx)(H2O)2(NO3)2] (2), and [Zn(anti-btx) (syn-btx)(H2O)2] (NO3)2 (3) [btx=1,4-bis(1,2,4-triazol-1-ylmethyl)benzene], have been prepared under room temperature. Their structures were characterized by elemental analysis, IR, single-crystal X-ray diffraction analysis and thermogravimetric (TG) analysis. 1 is a 1D serration chain; 2 is an infinite ladder 1D chain; and 3 is generated as an infinite 1D chain. The 1D chain of the three complexes are all formed 3D framework through hydrogen bondings and π–π stacking interactions.
