Zigzag double-strands consisting of "coordination-gallery, [Ag-3(No-3)(3)(Py2S)(2)center dot 2H(2)O]"

Abstract

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