Three metal–organic coordination polymers constructed by 1,4-bis(1,2,4-triazol-1-ylmethyl)benzene

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.
