Iron (II) complexes of 1-alkyl-2-(arylazo)imidazoles (p-R-C 6 H 4-N=N-C 3 H 2 NN-1-R′, R = H (a), Me (b), Cl (c) and R′ = Me (1/3), Et (2/4) have been synthesized and formulated as tris-chelates .) R Fe(Raai 2 3 + ′ They are characterized by microanalytical, conductance, UV-Vis, IR, magnetic (polycrystalline state) data. The complexes are low spin in character, 6 2 g t (Fe(II)) configurations.
