Abstract

Palladium(II) halides form five-coordinate PdC2,(TDAN) complexes with 1,4,7-thiadiazonines (TDAN), whereas platinum(II) chloride yields five coordinate [PtC2,(TDAN)] · n H2O complexes in the solid state and four-coordinate square planar [PtCl(TDAN)]CI · n H2O complexes in DMF solution. Platinum(IV) chloride reacts with TDAN to form six-coordinate [PtCl3(TDAN)]CI · n H2O octahedral complexes. 1.4.7-Thiadiazonine behaves as a tridentate ligand and coordinatesvia all three heteroatoms (S. N and N) forming three mutually adjacent five membered chelate rings with the metal ion.
