Two 1D polymeric chain structures, namely, {[Ag(3-impmd)]·(SbF
6)·CH
2Cl
2}
(
1) and {[Ag(3-impmd)]·(NO
3)·MeOH}
(
2), were assembled from the flexible organic spacer
N,N'-bis(3-imidazol-1-yl-propyl)-pyromellitic diimide (3-impmd)with AgSbF
6 and AgNO
3, respectively. Complex
1 crystallizes with the 1D chains displaying cross-like arrangement, while Complex
2 presents a triple-stranded helical structure, which is dictated by the anions and further assembled into 3D architectures via variousweak supramolecular interactions. The luminescent properties of both complexes were investigated in solution and solid state.
