    Notes: Reaction of 2-acetylpyridine 4-methylthiosemicarbazone (H4ML) with halides of zinc(II), cadmium(II), and mercury(II) afforded complexes of the form [M(H4ML)X2] [M = ZnII (1-3), CdII (4-6) or HgII (7-9); × = Cl, Br, or I]. Reaction of H4ML with K2PdCl4 and K2PtCl4 gave compounds of the form [M(4ML)Cl] [M = PdII (10) or PtII (11)]. In all the new compounds, which were characterized by elemental analyses, conductance measurements, and electronic, IR and 1H- and 13C-NMR spectroscopy, and by 113Cd-, 195Pt-, or 199Hg-NMR spectroscopy when relevant, the ligand is N,N,S-tridentate, coordinating to the metal centre through its pyridine and azomethine nitrogen atoms and its thiocarbonyl sulfur atom, as was confirmed by X-ray diffraction studies in the cases of 4· 2 DMSO, 5· 2 DMSO, 6· 2 DMSO, 7· 2 DMSO, 10, and 11. In in-vitro assays, only [Zn(H4ML)Cl2] and [Zn(H4ML)Br2] showed some sign of antifungal activity against Aspergillus niger or Paecilomyces variotii.Supporting information for this article is available on the WWW under http://www.wiley-vch.de/contents/jc_2005/1999/98381_s.pdf or from the author.

    Description / Table of Contents: The Crystal Structures of Triphenylarsin-p-toluene Sulfonylimine and of its Donor-Acceptor Complex [ZrCl4(Ph3AsNSO2Tol)]2The molecular structures of the title compounds are reported. In the donor-acceptor complex [ZrCl4(Ph3AsNSO2Tol)]2 the zirconium atoms are bridged by the oxygen atoms of the triphenylarsin-p-toluene sulfonylimine molecules, forming a centrosymmetric dimer with a puckered Zr2O4S2 eight-membered ring in the chair conformation.Ph3AsNSO2Tol: Space group P1, Z = 2, structure determination with 4 010 observed unique reflections, R = 0.036. Lattice dimensions at 19°C: a = 897.52(4), b = 1 071.82(6), c = 1 337,49(5) pm, α = 110.280(4)°, β = 98.814(4)°, γ = 109.872(4)°.[ZrCl4(Ph3AsNSO2Tol)]2: Space group P21/n, Z = 4, structure determination with 3 762 observed unique reflections, R = 0.078. Lattice dimensions at -60°C: a = 1 387.3(4), b = 1 434.9(2), c = 1 404.7(4) pm, β = 92.71(1)°.
    Notes: Es wird über die Molekülstrukturen der beiden Titelverbindungen berichtet. In dem Donor-Akzeptorkomplex [ZrCl4(Ph3AsNSO2Tol)]2 sind die Zirkoniumatome über die O-Atome der Triphenylarsin-p-toluolsulfonylimin-Moleküle zu einem zentrosymmetrischen Dimer mit einem Zr2O4S2-Achtring in der Sesselkonformation verknüpft.Ph3AsNSO2Tol: Raumgruppe P1, Z = 2, Strukturlösung mit 4 010 unabhängigen beobachteten Reflexen, R = 0,036.
