Mono and bis hexamethylenetetramine iron(III) chloride, Fe(N C ,H ) CI (I) and
Fe(N C ,H ) Cl (II) were synthesized by the reaction of iron(III) chloride and
hexamethylenetetramine (HMTA) in chloroform. Chemical analysis and spectral
results show the coordination of HMTA to the iron(III). Electronic transition spectra
of compound I and I1 were also studied in coordinating and noncoordinating solvents
