Metalorganic coordination networks

Polymeric structures based on networks of homoleptic eight-coordinate La(III) centers linked through 2,2 -bipyridine-A/ 77 -dioxide have been prepared, for example, by the reaction of La(CF3S03)3 and 2,2 - and 4,4 -bipyridine-A(A/ -dioxide in methanol at 20 °C [122]. The reaction of FeCl2, 1,10-phenanthroline and benzene-1,2,4,5-tetracarboxylate in water at 160 °C in a Teflon reactor produces a two-dimensional polymeric structure of [Fe(phenanthroline)-(benzenecarboxylate)] [123]. Multi-dimensional metalorganic coordination polymers with metal-aromatic interaction which exhibit strong photoluminescent behavior have been prepared by different Ag(I)-naphthalene-carboxylates with hexamethylenetetramine in CH2CI2 [124].
