Crystal and Molecular Structure of Tetrabutylammonium bis(1,3-dithiole-2-selone-4,5-diselenolato)nickelate(II) and -(III), [(n-C4H9)4N]2[Ni(dsise)2 and (n-C4H9)4[Ni(dsise)2]Syntheses and properties of metal(II) and metal(III) bis-chelates of 1,3-dithiole-2-selone-4,5-diselenolate (dsise), of the general type (Bu4N)n)M(dsise)2] (n =2 : M = Zn, Cd, Hg, Cu, Ni, Pd; n = 1: M = Ni, Au) are reported and compared with chelates of the isologue 1,3-dichalcogenole-2-chalcogenoe-4,5-dichalcogenolate (i. r., 13C-n. m. r., e. p. r., cyclovoltammetric data). The unexpected rearrangement during the syntheses of dsise and 1,3-dithiole-2-selone-4,5-diselenolate (dmise) is characterized by ab-initio SCF calculations. The x-ray structures of (Bu4N)2[Ni(dsise)2] (space group P21/c, a = 8.5556(13) Å, b = 15.0009(12) Å, c = 19.696(3) Å, β = 96.018(7)°, V = 2513.9(5) Å3, Z = 2) and Bu4N[Ni(dsise)2] (space group C2/c, a = 25.133(6) Å, b = 9.828(4) Å, c = 18.104(7) Å, β = 132.81(1)°, V = 3281(2) Å3, Z = 4) are given.
    Notes: Synthese und Eigenschaften von Metall(II) und Metall(III) Bis-Chelaten des 1,3-Dithiol-2-selon-4,5-diselenolats (dsise) vom Typ (Bu4N)n[M(dsise)2](n = 2: M = Zn, Cd, Hg, Cu, Ni, Pd; n = 1:M = Ni, Au) werden beschrieben und im Vergleich mit isologen 1,3-Dichalkogenol-2-chalkogenon-4,5-dichalkogenolat-Chelaten diskutiert (IR, 13C-NMR, EPR, Cyclovoltammetrie). Anhand von ab-initio-SCF-Rechnungen wird die bei der Synthese des dsise und des 1,3-Dithiol-2-selon-4,5-dithiolats (dmise) auftretende „Umlagerung“ charakterisiert. Die röntgenkristallographischen Daten von (Bu4N)2[Ni(dsise)2] (Raumgruppe P21/c, a = 8,5556(13) Å, b = 15,0009(12) Å, c = 19,696(3) Å, β = 96,018(7)°, V = 2513,9(5) Å3, (Z = 2) und von Bu4N[Ni(dsise)2] (Raumgruppe C2/c, a = 25,133(6) Å, b = 9,828(4) Å, c = 18,104(7) Å, β = 132,81(1)°, V = 3281(2) Å3, Z = 4) werden vorgestellt.

    Description / Table of Contents: 3-Diethylamino-5-phenyl-1,2,4-diselenazolium-tetrachloroniccolate(II)  -  Synthesis and StructureBis-(N′, N′-diethyl-N-benzoylselenoureato)nickel(II) reacts with diphosgene in benzene to 3-diethylamino-5-phenyl-1,2,4-diselenazolium-tetrachloroniccolate(II). Its structure is confirmed by RKSA and ESCA. The compound consists of cations, which are planar fivemembered rings and of tetrahedral tetrachloroniccolate(II) anions. The complex is isomorphic with 3-diethylamino-5-phenyl-1,2,4-dithiazolium-tetrachloroniccolate(II).

Die Verbindung besteht aus 1,2,4-Diselenazolium-Kationen, die als planare Fünfringe vorliegen und aus tetraedrischen Tetrachloroniccolat(II)-Anionen. Sie ist zu 3-Diethylamino-5-phenyl-1,2,4-dithiazolium-tetrachloroniccolat(II) isomorph.

    Description / Table of Contents: Coordination of Silver(I) by N,N-Diethyl-N′-benzoyl Thiourea in Solution and in the Solid StateSilver(I) reacts in dioxane/water solution with N,N-diethyl-N′-benzoyl thiourea HL to give cationic, neutral, and anionic complexes depending on the pH value, the molar ratio of the reactants and their concentrations. The ligand in these complexes coordinates in various ways. Complex stability constants have been determined by pAg and pH potentiometry. Representative complexes have been isolated in the solid state. One of them is a cyclic tetramer [AgL]4 the structure of which has been determined by X-ray diffraction.
    Notes: Silber(I) bildet mit N,N-Diethyl-N′-benzoyl-thioharnstoff HL in Dioxan/Wasser-Mischung, abhängig vom pH-Wert, dem molaren Verhältnis der Reaktanden und ihren Konzentrationen, kationische, neutrale und anionische Komplexe, in denen der Ligand in unterschiedlicher Weise koordiniert. Für diese Komplexe wurden pAg- und pH-potentiometrisch Stabilitätskonstanten bestimmt. Repräsentative Komplexe konnten in festem Zustand isoliert werden, darunter ein cyclischer Komplex [AgL]4, dessen Struktur durch Röntgenbeugung bestimmt wurde.
