Duhme, Anne Kathrin published the artcileLigand-deficient complexes of cadmium. Synthesis and spectroscopic characterization of molecular pentafluorophenyl cadmium thiolates and the structure of the cubane complex [{Cd(C6F5)(SBut)}4], HPLC of Formula: 22693-41-0, the publication is Zeitschrift fuer Naturforschung, B: Chemical Sciences (1994), 49(1), 119-27, database is CAplus.
In toluene, bis(pentafluorophenyl)cadmium(II) and thiols RSH (R = But, 2,4,6-Pri3C6H2, 2,4,6-But3C6H2) react to give soluble pentafluorophenyl cadmium thiolates [{Cd(C6F5)(SR)}n]. The compounds [{Cd(C6F5)(SBut)}4] (1).0.5 C6H5CH3, [{Cd(C6F5)(SC6H2Pri3-2,4,6)}n] (2).ca. 0.25 n C6H5CH3, and [{Cd(C6F5)(SC6H2But3-2,4,6)}n] (3).ca. 0.25 n C6H5CH3 were prepared in 65, 59 and 78% yields, resp. The structure of 1.0.5 C6H5CH3 was determined by x-ray crystallog. 1 Is a cubane-type complex with a {Cd4(¦Ì3-SBut)4}4+ core. Each Cd atom is coordinated by three bridging thiolato ligands and one terminal C6F5 group (Cd-S 2.62 ?, Cd-C 2.15 ? (mean values)). The central C atoms of the ButS– ligands of 1 show a remarkable low-field shift of their 13C NMR resonance (12.3 ppm relative to the value of the free thiol). A characteristic spectral feature of {Cd(C6F5)}+ complexes is the large value of the coupling constant 2J(19F,13C) of the ipso-C atom (1, 2: 68 Hz; 3: 67 Hz). The complexes [Cd(C6F5)(SR) + H]+, [Cd(SR)2+H]+, and [Cd2(SR)3]+ were identified in the CI mass spectra (iso-butane) of 2 and 3.
