“…Imidazole-containing ligands such as 1,4-bis(imidazol-1ylmethyl)benzene (bix) (Hoskins et al, 1997a,b;Fan et al, 2005), 1,1-(1,4-butanediyl)bis(imidazole) (bbix) (Ma et al, 2000;Duncan et al, 1996), 1,3,5-tris(imidazol-1-ylmethyl)benzene (tib) (Liu & Tong, 2002) and related species have been used to generate a rich variety of metal-organic architectures with interesting structural topologies and potential properties, as well as many hydrogen-bonding aggregates (Aakerö y et al, 2005(Aakerö y et al, , 2006Zhang, Gembicky et al, 2007;Xu et al, 2008). Considering the weak intermolecular forces among fluorinated compounds, Shreeve and co-workers have reported three novel coordination polymers constructed from transition metals with 2,3,5,6-tetrafluoro-1,4-bis(imidazol-1ylmethyl)benzene (Fbix) (Gao et al, 2006).…”
