New complex bearing end-to-end dicyanamide as a double bridging ligand: Crystallography study and magnetic properties

A new polymeric, two-dimensional compound [Fe(4,4’-bpy)(µ1,5-dca)2].0.24(4,4’-bpy).0.5(EtOH) (1), in which dca= dicyanamide and 4,4’-bpy = 4,4’-bipyridine, has been synthesized under solvothermal conditions and fully characterized by elemental analysis, FT-IR spectroscopy and X-ray single crystal diffraction. Structural analysis of compound 1 showed it is a novel two dimensional coordination polymer, constructed from repetition of 4,4’-bpy and dca as a bidentate bridging ligand. Using the co-ligand 4,4’-bpy, lead to completely different structure geometry and network, which confirms the substantial effect of co-ligand. Furthermore, magnetic properties have been performed to understand the correlation structure-properties.
