• Two novel triazole-Cu(II) coordination polymers have been isolated under solvo-thermal conditions.
• Variable-temperature magnetic susceptibility of 1–2 indicate weak anti-ferromagnetic interactions.
• 2 can effectively capture Cr2O72− in the water solutions and selectively capturing Congo Red in the methanol solutions.
In this work a flexible multi-dentate 1-(4-aminobenzyl)-1,2,4-triazole (abtz) ligand has been employed, two novel triazole-Cu(II) coordination polymers {[Cu(abtz)2(Br)2]·(H2O)2}n (1) and {[Cu(abtz)2]·(SiF6)·(H2O)2}n (2) have been isolated under solvo-thermal conditions. 1 is a 2D neutral CuII coordination polymer while 2 is 2D cation micro-porous CuII coordination polymer with the channel dimensionalities of 11.852(1) Å × 11.852(1) Å (metal-metal distances). Variable-temperature magnetic susceptibility data of 1 and 2 have been recorded in the 2–300 K temperature range indicating weak anti-ferromagnetic interactions. Further absorption properties of anion pollutants for 2 also have been investigated. 2 presents the novel example of cationic triazole-copper(II) coordination framework for effectively capturing anion pollutants Cr2O72− in the water solutions and selectively capturing Congo Red in the methanol solutions.
