Abstract
The one-dimensional coordination polymer [(H2O)(NO3)(2)CuFe(1)(2)(2)(NO3)(4)center dot 2.15MeCN center dot 5.85H(2)O](n) assembles when the pendant pyridine donors in [Fe(1)(2)](2+) (1 = 4`-(4-pyridyl)2,2`: 6`,2 ``-terpyridine) are treated with Cu(NO3)(2)center dot 3H(2)O, exemplifying [Fe(1)(2)](2+) as an expanded 4,4`-bipyridine ligand. In the solid state, the polymer chains are threaded through hydrogen-bonded macrocycles comprising coordinated and non-coordinated water molecules and nitrate ions, the macrocycles being motifs within interconnected sheets in the structure.
