Counter anion dependent symmetry of CuII–4-amino-1,2,4-triazole polymeric chains

Abstract
The symmetry changes and length of the symmetry independent part of [Cu(amtrz)3]n 2+ (amtrz = 4-amino-1,2,4-triazole) polymeric chains driven by different anions in crystals with BF4 (1), BF4 /SiF6 2− (2) and SiF6 2− (3) have been studied by single crystal X-ray method.
