    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).
    Notes: Bis-(N′, N′-diethyl-N-benzoylselenoureato)nickel(II) reagiert mit Diphosgen in Benzen zu 3-Diethylamino-5-phenyl-1,2,4-diselenazolium-tetrachloroniccolat(II), dessen Röntgenkristallstrukturanalyse und Röntgenphotoelektronenspektrum vorgestellt und interpretiert werden. 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.

Crystal and Molecular Structure of Tetramethylammonium-bis-[bis(1,3-dithiole-2-selone-4,5-diselenolato)nickelate]; [(CH3)4N] [Ni(dsise)2]2Syntheses and properties of dichalcogenolate chelates of the general type [(CH3)4N]n[ML2] (n ≤ 2; M = Ni, Pd, Pt); L = dmit (1,3-dithiole-2-thione-4,5-dithiolate), dmise (1, 3-dithiole-2-selone-4,5-dithiolate), dsit (1, 3-dithiole-2-thione-4,5-diselenolate), dsise (1, 3-dithiole-2-selone-4,5-diselenolate), dsis (1, 3-diselenole-2-selone-4,5-diselenolate) are reported. The effects of the chalcogen atom variation in these chelates are discussed by using UV/VIS, IR, EPR, cyclovoltammetric and conductivity data. The x-ray structure of [(CH3)4N][Ni(dsise)2]2 (space group Pccn, a = 7.427(1), b = 39.144(5), c = 11.836(1) Å) and the conductivity of the crystal (12 S cm-1 at room temperature) are given.

Anhand von UV/VIS-, IR-, EPR-, cyclovoltammetrischen und Leitfähigkeitsuntersuchungen werden die Auswirkungen der Chalkogenvariation in den Chelaten diskutiert. Die röntgenkristallographischen Daten von [(CH3)4N] [Ni(dsise)2]2 (Raumgruppe Pccn, a = 7,427(1), b = 39,144(5), c = 11,836(1) Å) und die Kristalleitfähigkeit (12 S cm-1, Raum-temperatur) werden vorgestellt.
