Abstract

Abstract: To observe anion impact on structural diversity of coordination architectures, three 1-D Ag(I) complexes with distinct features have been prepared, {[Ag(bpbib)2 (NO3 )]·C3 NH9 O)}n (1 ), [Ag2 (bpbib)2 ·(BF4 )2 ]n (2 ), and [Ag2 (bpbib)2 ·(ClO4 )2 ]n (3 ), by the reactions of 4, 4′-bis((2-(pyridin-2-yl)- 1 H-benzo[d]imidazol-1-yl)methyl)biphenyl (bpbib) with Ag(I) salts. Complex1 is a 1-D helical chain, whereas2 and3 bear ligand-unsupported Ag(I)···Ag(I) interaction-directed 1-D structural motif, with synergetic working of flexible organic linker and anions. All complexes exhibit strong triplet state emission at cryogenic temperatures, which profits from the reduction of nonradiative transitions. Abstract :
