Abstract
It has been demonstrated that the reaction of Cat[Ag[B12H12]] or [Ag2[B12H12]] with chelating ligands L (L = bipy, phen) leads to the selective formation of stable [(Ag2(L)2[B12H12]]n 1D polymers irrespective of the nature of cation (Cat) in the starting reagent, the ratio of the reaction components, and the solvent used. The structures of [Ag2(bipy)2[B12H12]]n · 2CH3CN and [Ag2(phen)2[B12H12]]n · DMF have been determined by X-ray crystallography. It has been demonstrated that the [B12H12]2− anion in polymer chains acts as a bridging ligand coordinated to silver atoms through edges or through an edge and a vertex of the icosahedron. The Ag–B(H) and Ag–H(B) distances are within 2.638(3)–3.074(3) and 1.90–2.80 Å, respectively. These complexes are the first examples of 1D coordination polymers based on the [B12H12]2− anion and azaheterocyclic ligands L.
