Synthesis and characterization of [Fe(μ-Cl)2(phen)] n and [Fe(H2O)3(phen)SO4]

[Fe(μ-Cl)2(phen)] n (1) and [Fe(H2O)3(phen)SO4] (2) have been synthesized and characterized by single crystal X-ray diffraction analysis, IR and UV spectra. Complex 1 crystallizes in monoclinic system with space group of C 2/c and 2 crystallizes in monoclinic system with space group of P 21/c. The structure of 1 shows that each Fe(II) coordinates with one phen and four chlorides forming a distorted octahedral environment, and [Fe(μ-Cl)2(phen)] as a repeating unit forms a one-dimensional chain. The structure of 2 shows that each Fe(II) coordinates with one , one 1,10-phen and three H2O molecules; the crystal architecture is stabilized by hydrogen bonds and π–π interactions.
