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 one- dimensional (1D) double-helical coordination polymer {(Ag(4-pbt))(NO3)}� (1) formed by interchain C-H � su- pramolecular 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,  stacking, and C H 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-yl- based pyridyl ligands plays an important role on the final structures of relevant coordination complexes.
