1,2,3- triazoles are 5-membered heterocyclic compounds that are used in many drugs, dyes, corrosion inhibitors and organic synthesis intermediates. Reach to straightforward procedure for synthesis of this important compounds is an attention grabbing issue among organic synthesis researchers. Applying of ball-mill prepared [Cu₂ (BDC)₂ (DABCO)] as a high stable, low leaching, clean and recyclable porous coordination polymer (PCP)  catalyst  for synthesis of triazole derivatives  proved to be a practical and facile procedure that was carrying out in water as a green solvent. Low reaction time, mild and non-toxic reaction media and high yield of desire product is other aspects of mentioned procedure.
