A new 3D supramolecular architecture constructed from the overlapping of ladder-like 1,2,4-triazole-bridging Ag(I)chains

摘要

A new 1D ladd er-like chain,{[Ag2(aptr)2](SiF6)}_n·5nH2O(aptr=4-amino-3-(pyrid-4-yl)-1,2,4-triazole),was synthesized with structure and fluorescence characterized.The skeleton chain based on a fundamental repeating unit[Ag(aptr)]comprises of two kinds of 6-and 14-membered rings.The overlapping of two sets of ladders along the a+b and a-b vectors produces elliptic channels with SiF_6~(2-)anchoring in.A 3D supramolecular architecture is formed by hydrogen bondings between SiF_6~(2-)and aptr.Three lattice water molecules are connected into a water chain through the hydrogen bondings among them.
