ABSTRACT

The reaction of AgNO3 with 1-(4-pyridylmethyl)-1H-benzotriazole (4-pbt) afforded a photoluminescent onedimensional (1D) double-helical coordination polymer {[Ag(4-pbt)](NO3)}∞ (1) formed by interchain C-H...psupramolecular interactions of the single-helical chains. Adjacent 1D double-helical motifs aforementioned were assembled into different two-dimensional (2D) sheets from the different crystallographic directions, respectively, by the co-effects of Ag...O, C-H···O H-bonding, p...p stacking, and C-H...p supramolecular interactions. In comparision with the previous finding, the present work reveals that the N-donor spatial position of pendant pyridyl group in such benzotriazol-1-ylbased pyridyl ligands plays an important role on the final structures of relevant coordination complexes.
