Abstract in another language
When reacting the organic functionalized tin selenide clusters [(SnR1)3Se4Cl] (A, R1=CMe2CH2C(O)Me) or [(SnR1)4Se6] (B) with (SiMe3)2Se and [Ag(PPh3)3Cl] at ?78?°C in CH2Cl2, a microcrystalline intermediate (compound 1) precipitates, which was investigated by magic angle spinning (MAS) NMR spectroscopy, powder X-ray diffraction (PXRD), energy dispersive X-ray (EDX) spectroscopy, and quantum chemistry calculations, to derive information about its composition and structure. Compound 1 re-dissolves under reorganization into the organo-functionalized Ag/Sn/Se cluster compound [Ag6(?6-Se)(Ag8Se12){(R1Sn)2Se2}6] (2), or the mixed-valence cluster [(AgPPh3)2(SnIICl)2Se2{(R1SnIV)2Se2}2] (3), depending on the presence or the exclusion of daylight, respectively. The addition of N2H4?H2O to a solution of 1 yields selectively [Ag7(?7-Se)(Ag7Se12){(R2Sn)2Se2}6] (4, R2=CMe2CH2C(N2H2)Me), the Ag/Sn/Se core of which is isomeric to that of 2. 2?4 were characterized by X-ray diffraction. NMR spectroscopic studies on solutions of 1 indicate the co-existence of different species.
