Compounds of general formula FeX2(L) L=2,6-bis(3,5-dimethyl-N-pyrazolyl)pyridine, C15H17N5; bis[3,5-dimethyl-N-pyrazolyl)methyl]-isopropylamine, C15H25N5; bis(benzimidazol-2-yl-methyl)amine, C16H15N5, 1,3-bis(benzimidazolyl)propane, C17H16N4; bis(benzimidazolyl-2-methyl)ether, C16H14N4O; bis(benzimidazolyl-2-methyl)thioether, C16H14N4S} have been synthesized by reacting the amine with Fe4Cl8(THF)(6) or FeI2(CO)(4) in toluene. The complexes FeCl2(Cl15H17N5).MeCN and FeCl2(C16H15N5)(MeOH) have been characterized by single crystal X-ray diffraction together with the parent triamines, C15H17N5 and C16H15N5, for comparison. The reaction of FeI2(CO)(4) with bis(benzimidazolyl-2-methyl)thioether, C16H14N4S, led to the product of partial carbonyl substitution Fel(2)(CO)(2)(C16H14N4S). (C) 2002 Elsevier Science B.V.
