Morpholine-4-carbodithioate (mdtc) complexes of titanium(IV), vanadium(IV), chromium(III), manganese(III), iron(III), cobalt(III), nickel(II), copper(II), zinc(II), and cadmium(II) have been prepared and characterised by analysis and magnetic and spectroscopic techniques. The complexes are of the type M(mdtc)n, where n is the oxidation state of the metal ion except for vanadium(IV), where the complexing species is the VO2+ ion. Some adducts with the parent base morpholine are also reported.
