Coordination Chemistry of 1,3-Dithiole-2-one-4,5-dithiolate (dmid) - Comparison with 1,3-Dithiole-2-thione-4,5-dithiolate (dmit). Crystal and Molecular Structure of Tetrabutyl-ammonium bis (1,3-dithiole-2-one-4,5-dithiolato)nickelate(III), (n-C4H9)4N[Ni(dmid)2]Synthesis and properties of metal(II) and/or metal(III) bis-chelates of 1,3-dithiole-2-one-4,5-dithiolate (dmid), of general type An[M(dmid)2] (A = Bu4N+, Ph4As+; M = Zn, Cd, Hg, Cu, Ni, Pd, Au, Fe; n = 1, 2) are described. 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:
Synthese und Eigenschaften von Metall(II)- und/oder Metall(III)-bis Chelaten des 1,3-Dithiol-2-on-4,5-dithiolats (dmid) vom Typ An[M(dmid)2] (A = Bu4N+, Ph4As+; M = Zn, Cd, Hg, Cu, Ni, Pd, Au, Fe; n = 1, 2) werden beschrieben. Anhand der IR-, 13C-NMR-, EPR-Spektren und Cyclovoltammogramme dieser Chelate und analoger Chelate des 1,3-Dithiol-2-thion-4,5-dithiolats (dmit) sowie EHT-Rechnungen werden die Auswirkungen der Substitution von Schwefel durch Sauerstoff an der 2-Position diskutiert. Die Röntgenkristallstrukturanalyse von Bu4N[Ni(dmid)2] ergab die Raumgruppe P1 mit 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)° und Z = 2.
