    Notes: Crystal and Molecular Structure of 4,5-Dibenzoylseleno-1,3-diselenole-2-seloneThe crystal and molecular structure of 4,5-dibenzoylseleno-1,3-diselenole-2-selone is described. The compound crystallizes in the monoclinic space group P21/c with a = 9.704, b = 10.839, c = 17.726 [Å], β = 93.43° and Z = 4. The structure is compared with that of the analogous „all-sulfur“ compound. The crystal packing of the heterocycle studied shows surprisingly short intermolecular distances between neighbouring selone groups.

    Description / Table of Contents: Electrochemical Reduction of CSSe and CSe2 in Dimethylformamide: Heterocyclic 1,2-Dichalcogenolates and their Coordination ChemistryStarting from carbon diselenide or carbon selenidesulfide the electrochemical preparation (electrosynthesis) of heterocyclic dichalcogenolates C3X52- (X = Se: dsis; X = S/Se: C3SxSey2-) is outlined. The 1,2-dichalcogenolate compounds were isolated and characterized as dibenzoyl derivatives. Bis- or tris-chelates of general type Am[M(C3X5)n] (with A = Bu4N+, Ph4As+; M = ZnII, PtII, PdII, NiIII, CuIII, AuIII, InIII; X = Se, S/Se; m = 1, 2, 3; n = 2, 3, respectively) are available directly from methanolic solutions of the dibenzoylates after hydrolytic cleavage of the latter with sodium methanolate. In addition bis-chelates Bu4N[Ni(C3X5)2] (X = Se, S/Se) have been characterized by cyclovoltammetry and epr spectroscopy and compared with the corresponding all-sulfur ligand compound Bu4N[Ni(dmit)2] (X = S). Arguments are given for the fact that the allselenium ligand dsis (X = Se) yields the CuIII or NiIII chelate at once whereas with dmit using identical conditions the metal(II) compounds are formed.
    Notes: Ausgehend von Selenkohlenstoff und Selenschwefelkohlenstoff wird die elektrochemische Darstellung heterocyclischer Dichalkogenolate C3X52- (X = Se: dsis; X = S/Se: C3SxSey2-), die als Dibenzoylverbindungen isoliert und charakterisiert werden, beschrieben. Aus den mit Alkalimethanolat erhaltenen Verseifungslösungen dieser Dibenzoylverbindungen sind Metall-bis- und -tris-Chelate der heterocyclischen 1, 2-Dichalkogenolate vom Typ Am[M(C3X5)n] (A = Bu4N+, Ph4As+; M = ZnII, PtII, PdII, NiIII, CuIII, AuIII, InIII; X = Se, S/Se; m = 1, 2, 3; n = 2, 3) unmittelbar zugänglich. Cyclovoltammetrisch und mittels EPR werden die Nickel(III)-Verbindungen Bu4N[Ni(C3X5)2] (X = Se, S/Se) charakterisiert und der analogen Schwefelverbindung Bu4N[Ni(dmit)2] (X = S) gegenübergestellt. Für die bei der Chelatisierung mit dsis (X = Se) beobachtete Metall(II)-Metall(III)-Oxydation bei Kupfer und Nickel werden Argumente erörtert.

By comparison of the i.r., 13C-n.m.r., e.p.r. spectra, cyclovoltammetric data, and EHT calculations of chelates of dmid and those of the chelates of 1,3-di-thiole-2-thione-4,5-dithiolate (dmit) the consequences of oxygen for sulfur substitution on position 2 of the heterocyclic ligand upon the dithiolene behavior of the complexes are discussed. The x-ray crystal structure analysis of Bu4N[Ni(dmid)2] yields a space group P1 with a = 11.925(2), b = 12.095(2), c = 12.164(2) Å, α = 97.88(1), β = 109.82(1), γ = 97.21(2)° and Z = 2.

    Notes: The coordination chemistry of two crown thioethers 2,5,8,10,12-pentathiabicyclo[7.3.0]dodeca-1)9)-ene-11-thione (L) and -11-one (L') with Ag1 has been investigated by structural methods. Both thioethers act as tridentate ligands coordinating the silver ion in a trigonal fashion. In the case L, the 11- thione sulfur is coordinated additionally by another silver ion, to yield a polymeric chain with a distorted-tetrahedral geometry about the metal ion. Despite differing only in its carbonyl chalcogen, L' forms six-coordinated, monomeric complexes.
