Abstract

Reactions of the organotin selenide chloride clusters [(R Sn ) Se Cl] (A, R =CMe CH C(O)Me) or [(R Sn ) Se ] (B) with [Cu(PPh ) Cl ] yield cluster compounds with different inorganic, mixed-valence core structures: [Cu Sn Sn Se ], [Cu Sn Sn Se Cl ], [Cu Sn Sn Se ], [Cu Sn Sn Se Cl ], and [Cu Sn Se ]. Five of the compounds, namely [(CuPPh ) {(R Sn ) Se }] (1), [(CuPPh ) Sn {(R Sn ) Se } ] (2), [(CuPPh ) (Sn Cl) {(RSn ) Se } ] (3) [(CuPPh ) (Sn Cu ){(R Sn ) Se } ] (4), and [Cu(CuPPh )(Sn Cu ){(R Sn ) Se } ] (5) are structurally closely related. They are based on [(CuPPh ) {(RSn ) Se } ] aggregates comprising [(RSn ) Se ] and [CuPPh ] building units, which are linked by further metal atoms. A sixth compound, [(CuPPh ) (Sn Cl) {(R Sn Cl)Se } ] (6), differs from the others by containing [(RSn Cl)Se ] units instead, which affects the absorption properties. The compounds were analyzed by single-crystal X-ray diffraction, NMR and Sn Mössbauer spectroscopy, DFT calculations as well as optical absorption experiments.
