Two novel three-dimensional coordination polymers with [Ag(CN)2]− as bridging ligands: synthesis and structural characterization of {KMn[Ag(CN)2]3(H2O) }n and {Mn[Ag(CN)2]2(bpy)2}n (bpy=4,4′-bipyridine)

Two novel three-dimensional coordination polymers {KMn[Ag(CN)2]3(H2O)}n 1 and {Mn[Ag(CN)2(bpy)]2}n 2 have been prepared and structurally as well as magnetically characterized. In both compounds, the three-dimensional networks are constructed entirely by coordinative linkages with all the CN− anions of [Ag(CN)2]−, bpy and water ligands involved in bridging and the novel 3-D structure of 1 is unprecedented.
