A Double-Helical Silver(I) Coordination Polymer Based on 1-(4-pyridylmethyl)-1H-benzotriazole: Synthesis, Crystal Structure and Luminescent Property

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···π supramolecular 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, π···π stacking, and C-H···π 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.
