The silylated ferrocenyl selenium reagent 1,1′-Fe(η5- C5H4SeSiMe3)2 has been used for the high yield formation of the phosphine-ligated copper complexes Cu 2(fcSe2)(P/Pr3)2 (1) and Cu 4(fcSe2)2(PnPr3)4 (2) from solublilized CuOAc, as determined by single-crystal X-ray diffraction. The incorporation of a source of Se2- into the reaction scheme with the reagent Se(SiMe3)2 yields the mixed selenide/ ferrocenyldiselenolate cluster [Cu20Se6(Se 2fc)4(PnPr3)10] (3). Partial substitution of the PnPr3 ligand shell in 3 with the phosphinothiol Ph 2P(CH2)3SH leads to an expansion of the framework and the high yield formation of the crystallographically characterized cluster Cu36(fcSe2)6Se12(PnPr 3)10(Ph2P(CH2)3SH) 2 (5), which contains surface alkylthiol groups on a copper-selenium core.
