Coordination behaviour of benzothiazolines towards iron(II)

Summary This paper describes the synthesis and structural features of iron(II) complexes of some biologically active benzothiazolines derived by the condensation of various aldehydes and ketones such as pyridine 2-aldehyde, furfuraldehyde, thiophene-2-aldehyde, indole-3-carboxaldehyde, benzil, biacetyl, glyoxal, and terpthaldehyde with 2-aminothiophenol. An attempt has been made to characterize the resulting complexes by elemental analysis, conductance measurement, molecular weight determination and electronic, infrared,¹H and¹³C n.m.r. spectral studies. An octahedral geometry has been suggested on the basis of magnetic measurements and Mössbauer spectra.
