Early examples of metallic grids employed different bidentate and tridentate ligands based on bi(pyridines) (Youinou, et al., 1992) and terpyridines (Garcia, et al., 1999).
Among the reported structures, organic ligands with carboxylate play an important role in coordination chemistry and can adopt various binding modes such as monodentate, chelating one metal center, bridging two metal centers in a synsyn, syn-anti and anti-anti configuration, and bridging two metal centers in a tridentate form [10-11].

Further, an excessive amount of [Fe.sup.3+] will break the ideal [Fe.sup.3+]-CO[O.sup.-] tridentate coordinate equilibrium, the optimal state as strength enhancer, and shift it to less robust states consisting on bi- and/or mono-dentate counterparts.
