Abstract

en

Complexes having the empirical formulae M(DEBCTA)2X2 (M = Zn or Cd, X = Br or I, DEBCTA = N,N-diethylbenzenecarbothioamide), Zn(DEBCTA)Cl2, Cd2(DEBCTA)Cl4 and Hg(DEBCTA)X2 (X = Cl, Br or I) were made by reaction of zinc, cadmium or mercury dihalides in ethanol or 1,2-dichloroethane. All complexes have been characterized by elemental analysis, conductance and molecular weight measurements and by infrared and 1H-NMR spectral studies. In addition, the structure of [Hg(DEBCTA)I2]2 has been determined by single-crystal X-ray crystallography and refined to a conventional R factor of 0.097. The compound crystallizes in the monoclinic space group P21/n with a = 1383.9(2), b = 834.3(1), c = 1418.2(2) pm, β = 101.03(1)° and Z = 2. The molecule was found to have a dimeric structure involving two asymmetrical iodine bridges in which the Hg atom lies a tetrahedral environment and the ligands lie mutually trans with respect to one another.

Komplexe von IIB Metall-halogeniden mit N,N-Diethylbenzocarbothioamiden. Kristallstruktur von [Hg{C6H5C(S)N(C2H5)2}I2]2

Verschiedene Komplexe von N,N-Diethylbenzocarbothioamide (DEBCTA) mit MX2 (M = Zn, Cd oder Hg und X = Cl, Br oder I) wurden hergestellt und mittels Elementaranalyse, Molgewichtsbestimmung, IR, 1H-NMR-Spektren und konduktometrischen Messungen untersucht. Die Kristallstruktur von [Hg(DEBCTA)I2]2 wurde mit Hilfe von Röntgenbeugungsdaten ermittelt (2402 beobachtete unabhängige Reflexe, R = 0,097). [Hg(DEBCTA)I2]2 kristallisiert monoklin in der Raumgruppe P21/n mit zwei Formeleinheiten pro Elementarzelle; Gitterkonstanten a = 1383,9(2), b = 834,3(1), c = 1 418,1(2) pm, β = 101,03(1)°. Im dimeren Komplex sind die verzerrt-tetraedrisch koordinierten Hg-Atome von je einem S-Atom des Liganden, einem terminalen I-Atom und zwei verbrückenden I-Atomen umgeben.
