Photophysical Properties of Three-Dimensional Transition Metal Tris-Oxalate Network Structures... 

The first structure of a three-dimensional transition metal network incorporating the oxalate ion was that of [Ni(phen)3][KCo (ox)3] 2H20 (phen= 1,10-phenanthroline) reported by Snow and co-workers in 1971. The true dimensionality of this compound, however, went unrecognized during this period, and the potential of oxalate ions to form three-dimensional networks was not fully realized until 1993, when Decurtins et al. published the crystal structure of the iron(II)-oxalato complex with tris(2,2 -bipyridine)iron(II) cations. This compound has an overall stoichiometry of [Fe (bipy)3] [Fe 2(ox)3] " and forms a three-dimensional anionic polymeric network that is best described with the three-connected decagon network topology. A view of this anionic network is shown in Figure 43.
