A new tri-nuclear Ag(I)-MOF as potential energetic materials constructed using (1e)-N′-hydroxy-2-(1H-1,2,4-triazol-1-yl) ethanimidamide and nitrates

The reaction of silver nitrate with (1e)-N'-hydroxy-2-(1H-1,2,4-triazol-1-y1) ethanimidamide (HTE) at room temperature affords a new 3D metal-organic frameworks, {[Ag-3(HTE)(2)(NO3)(2)]center dot NO3}(n) (1). Single crystal X-ray diffraction analysis reveals that the three silver metal centers are bridged by two HTE ligands and Ag-Ag strong interactions in 1. The bridges provided through the nitrogen atoms on triazole-ring and the nitrogen atoms of the ethanimidamide resulted in a trinuclear units {Ag-3(HTE)(2)} linked metal organic framework (MOF) structure. The MOF is displaying the trinuclear units that are connected via nitrates to give a 3D network. There are free nitrates incorporated in the channels of the MOF. (C) 2017 Published by Elsevier B.V.
