Abstract

We report the synthesis and full characterisation of a family of chains each exhibiting an alternating [M–Na–M–]n (M = Mn3+ or Fe3+) 1-D topology linked via the 2,2′-biphenol ligand along with various N-donor co-ligands such as pyridine, 3-picoline and 2,2-bipyridine. The chains [Na2Mn2(biphen)4(py)3(EtOH)2]n (1), [Na2Mn2(biphen)4(3-cnp)2(EtOH)3]n (5), [{Na2Mn2(biphen)4(4-Et-py)3(EtOH)2}·EtOH]n (6) and [NaFe(biphen)2(2,2-bipy)(EtOH)2] (8) are connected into 1-D arrays via predominantly covalent bonds while their siblings [Na(BiphenH2)(EtOH)x(H2O)y][M(biphen)2(L)2]n (M = Mn3+, L = 3-picoline, x = 3, y = 0 (2); M = Fe3+ L = 3-picoline, x = 3, y = 0 (3) and M = Mn3+, L = 4-cyanopyridine, x = 2, y = 1 (4)) are linked via ionic bonds along with strong hydrogen bonding interactions.
