The preparation and spectral and magnetic properties are reported for complexes of cobalt(II) with thiomorpholine. A comparative study has been made of the donor ability of nitrogen and sulphur atoms in the complexes. In an attempt to correlate the behaviour of thiomorpholine and morpholine with respect to divalent cobalt, work on cobalt(II)–morpholine complexes has been extended. The compounds CoX2L2, X = halide, L = thiomorpholine or morpholine, have been shown to be pseudo-tetrahedral, whereas when X = thiocyanate the compounds can be regarded as pseudo-octahedral involving thiocyanate bridging. I.r. results suggest that thiomorpholine is coordinated to cobalt through the nitrogen rather than the sulphur atom.
