Abstract
The preparations are reported of complexes of pyrimidine-2-thione (Hpymt) with halides of MnII, FeII, CoII, NiII, ZnII and CdII. The complexes have stoicheiometry ML2X2. A combination of X-ray, electronic spectral, i.r., e.s.r:, and, for iron, Mössbauer studies shows that, in most cases, the sulphur atom, as well as the non-protonated ring nitrogen atom, of the thione ligand co-ordinates to the metal to give a four-membered chelate ring. Some inner complexes [M(pymt)2](M = Co, Ni, or Zn) are also reported.Keywords
