A Spectroscopic Investigation of Some Iron II Complexes

Abstract

<p> A number of complexes FeX2Ln (X = Cl, Br; L = formamide, N-methylformamide, N,N-dimethylformamide, acetamide, benzamide, isobutyramide, urea, N-methylurea, N,N'-dimethylurea, thioacetamide, thiourea, N-methylthiourea, N,N'-dimethylthiourea, benzothiazole, aniline) have been prepared and investigated by means of Mossbauer and infrared spectroscopy and magnetic measurements. It has been possible to distinguish firstly between 4-coordinate and 6-coordinate complexes and secondly between a number of different types of 6-coordinate complexes.</p>
