Zigzag Double-Strands Consisting of “Coordination-Gallery, [Ag3(NO3)3(Py2S)2•2H2O]”

Zigzag silver(I) single-strands connected by 4,4ʹ-dipyridyl sulfide are bridged via weak (pi)-(pi) and AgI-AgI interactions to generate subtle double-strands that exhibit the most plentiful and characteristic coordination modes. The compound gives an intense and broad emission ((lamda)max at 561 nm) which is yellow luminescence.
