The ligand mn15S5 was synthesized for the first time and characterized by X-ray diffraction. With silver(I) perchlorate and silver(I) tetrafluoroborate it forms the chiral complexes [Ag(mn15S5)]ClO4·CH3NO2 (2) and [Ag(mn15S5)]BF4·CH3NO2·0.25H2O (3) with half-sandwich moieties. AgI is located in a distorted tetrahedral coordination environment, involving three sulfur atoms of the crown cycle and a fourth one of the adjacent half-sandwich moiety, forming a helical structure. The reaction of Hg(ClO4)2 with mn13S4 yielded the dinuclear complex [Hg2(mn13S4)3](ClO4)4 (4) containing two half-sandwich moieties with a third ligand molecule as a bridging unit. Mercury(II) chloride and mercury(II) iodide react with mn12S4 and mn13S4 to form complexes of the general composition [HgX2(L)] (X = Cl, I; L = mn12S4, mn13S4): [HgCl2(mn12S4)] (5), [HgI2(mn12S4)] (6), [HgCl2(mn13S4)] (7) or [HgX2(L)2] (X = I; L = mn13S4): [HgI2(mn13S4)2] (8). Only one or two sulfur atoms of the ligand are involved in the complexation, and chain or ribbon structures are formed. In these compounds the HgX2 units (X = Cl, I) are preserved, coordinated by sulfur atoms of bridging mn12S4 or mn13S4 ligands. In all complexes of this type, the metal atoms are not coordinated inside the cavity, but in an exocyclic mode, because the diameter of the macrocycle is too small. Additionally, the PtCl2 complex of mn12S4 was investigated, where PtII is coordinated in an exocyclic mode forming the complex [PtCl2(mn12S4)] (9). Two of the four sulfur atoms of the macrocycle are bonded to the metal giving together with both chlorine atoms a square-planar coordination geometry. Together with a long-range interaction with a further sulfur atom of the macrocycle a square-pyramidal coordination environment is formed.}, language = {de} } @article{UhlemannDuvinageSchilde2008, author = {Uhlemann, Jacqueline and Duvinage, Brigitte and Schilde, Uwe}, title = {Kontexte und Kompetenzen : Komplexverbindungen experimentell erkunden}, issn = {1617-5638}, year = {2008}, language = {de} } @article{GroboschSchildeTiersch2006, author = {Grobosch, Thomas and Schilde, Uwe and Tiersch, Brigitte}, title = {Abtrennung von Arsen und anderer Schwermetalle mit impr{\"a}gnierten Adsorberpolymeren - teil 2: Abtrennung von Blei, Kupfer, Nickel und Zink}, issn = {0009-286X}, doi = {10.1002/cite.200500171}, year = {2006}, language = {de} } @article{WenzelWehseSchildeetal.2004, author = {Wenzel, Barbara and Wehse, Burkhard and Schilde, Uwe and Strauch, Peter}, title = {1,2-Dithioquadratato- und 1,2-Dithiooxalatoindate(III) = 1,2-dithiosquarato- and 1,2-dithiooxalatoindates(III)}, year = {2004}, abstract = {Indium(III) chloride forms in water with potassium 1,2-dithiooxalate (dto) and potassium 1,2-dithiosquarate (dtsq) stable coordination compounds.
