(PPh4)[(ReO2S2)CuI] and (NEt4)2[ReOS3)Cu3Cl4]: Fixation of the up to now not Isolated Ions [ReO2S2]- and [ReOS3]- Utilizing the Stability of the CuS2(Re) and Cu3S3(Re) Fragments(PPh4)[(ReO2S2)CuI] (1) and (NEt4)2[ReOS3)Cu3Cl4] (2) containing the up to now not isolated oxothioperrhenate ions [ReO2S2]- and [ReOS3]- as ligands, have been prepared by the reaction of (NEt4)[ReS4] with PPh3 and CuI in acetone in the presence of (PPh4)I ((1)) or with CuCl in CH2Cl2 in the presence of (NEt4)Cl ((2)), respectively. 1 and 2 have been characterized by X-ray structure analysis, elemental analysis and spectroscopic studies (IR, UV/Vis). The electronic spectra show bands which can approximately be assigned to interesting low-energy charge-transfer-transitions of the type d(Cu) → d(Re).For crystal data see Inhaltsübersicht.
Notes:
(PPh4)[(ReO2S2)CuI] (1) und (NEt4)2[(ReOS3)Cu3Cl4] (2), die die bisher nicht isolierten Oxothioperrhenat-Ionen [ReO2S2]- und [ReOS3]- als Liganden enthalten, wurden durch Reaktion von (NEt4)[ReS4] mit PPh3 und CuI in Aceton in Gegenwart von (PPh4)I ((1) bzw. entsprechend mit CuCl in CH2Cl2 in Gegenwart von (NEt4)Cl ((2) erhalten. 1 und 2 wurden durch Einkristall-Röntgenstrukturanalyse, Elementaranalyse, sowie spektroskopische Untersuchungen (IR, UV/Vis) charakterisiert. In den Elektronenspektren findet man Banden, die interessanten niederenergetischen Charge-Transfer-Übergängen des Typs d(Cu) → d(Re) näherungsweise zugeordnet werden können.Kristalldaten: 1P21/n, a = 1162,2(4), b = 1395,7(6), c = 1612,3(9)pm, β = 96,53(4)° V = 2598(2) · 106pm3, R = 0,049 für 4623 unabhängige Reflexe (F0≥4,0σ(F0)).2C2/c, a = 2059,0(5), b = 1352,9(3), c = 2217,1(5)pm, β = 90,26(22)° V = 6176(2) · 106pm3, R = 0,080 für 3162 unabhängige Reflexe (F0≥4,0σ(F0)).
