The reaction of the bidentate ligand 2,3,5,6-tetramethyl-1,4-diisocyanobenzene (Me4dib) with (phthalocyaninato)iron(II) and -ruthenium(II) (PcM, M = Fe, Ru) yields, depending on the reaction conditions, bisaxially coordinated monomeric derivatives of the stoichiometry PcM(Me4dib)2; 1, M = Fe; 2, M = Ru, or one-dimensional bridged polymeric chain structures of the formula n; 3, M = Fe; 4, M = Ru. 2,3,5,6-Tetrachloro-1,4-diisocyanobenzene can also be used as coordinative ligand to form the polymers 5 - 7.Synthesis of 3 and 4 is also possible starting with 1 and 2 in solution or in solid state.The polymerization in solution can be followed by 1H NMR spectroscopy.The intermediates formed are structurally characterized.The structures 1 - 7 are in agreement with additional TG/DTG/DTA-, 57Fe-Moessbauer, and IR measurements.Despite large differences in dc conductivity of the parent compounds PcFe and PcRu, the ligand-bridged compounds n (L = bidentate ligand) exhibit almost similar conductivities.
