    Description / Table of Contents: Trithiooxalate as Varying Bridging Ligand - Crystal and Molecular Structure of μ-Trithiooxalato-bis[bis(triphenylphosphane)copper(I)]Due to its design, trithiooxalat (trto) as a multidentate, chalcogen-rich ligand allows different coordination possibilities. In contrast to the corresponding dinuclear silver complex [(Ph3P)2Ag]2(trto), which is side-on(S,S′)/end-on(S′,S″) coordinated, the title complex is exclusively side-on (S,S′ and S″,O) coordinated involving the oxygen donor atom. [(Ph3P)2Cu]2(trto) crystallizes in the triclinic space group P1 (No. 2) with a = 10.195(2), b = 13.090(3), c = 13.450(3) Å, α = 116.10(2)º, β = 90.10(2)º, γ = 101.49(2)º, and Z = 1. The bridging ligand with its nonsymmetrical donor atom set is disordered around the centre of symmetry (inversion centre).
    Notes: Trithiooxalat (trto) bietet als vielzähniger, chalkogenreicher Ligand aufgrund seiner Struktur und seines Donoratomsatzes vielfältige Koordinationsmöglichkeiten. Im Gegensatz zum entsprechenden Silber-Zweikernkomplex [(Ph3P)2Ag]2(trto), der simultan side-on(S,S′)/end-on(S′,S″) koordiniert, liegt im Titelkomplex ausschließlich side-on(S,S′ bzw. S″,O) Koordination unter Einbeziehung des Sauerstoff Donoratoms vor. [(Ph3P)2Cu]2(trto) kristallisiert in der triklinen Raumgruppe P1 (No. 2) mit a = 10,195(2) Å, b = 13,090(3) Å, c = 13,450(3) Å, α = 116,10(2)º, β = 90,10(2)º, γ = 101,49(2)º und Z = 1. Der bezüglich seines. Donoratomsatzes unsymmetrische Brückenligand ist um das Symmetriezentrum (Inversionszentrum) fehlgeordnet.
