“…Thus, while the Cu 6 In 3 cluster is described as having a central [Cu 6 S 4 ] core, 3 has an inner [In 8 S 13 ] framework. The structure of 3 is very similar to that of two recently reported copper−indium−selenide clusters [Cu 6 In 8 Se 13 Cl 4 (PPh 3 ) 6 (CH 8 O)] and [Cu 6 In 8 Se 13 Cl 4 (P n Pr 2 Ph) 12 ] ( II ) 6a…”

“…The UV spectrum for a solution of 3 displays a weak maximum at 400 nm, with the onset of absorption at 490 nm, mirroring observations for the related selenium complex [Cu 6 In 8 Se 13 Cl 4 (PPh 3 ) 6 (OC 4 H 8 )] 6a. Solid-state diffuse reflectance spectra of 3 display a similar profile.…”

“…Although the ratio of Hg:Cu:S in 1 is 3:4:5, versus the 3:6:6 ratio of these elements in the reaction mixture, the preformed S−Cu bond in 4a is required for the formation of 1 , as simple mixtures of 1:0.5:5 CuOAc:Hg(OAc) 2 :PPr 3 and S(SiMe 3 ) 2 do not generate the ternary cluster. This contrasts with the synthetic route to the recently reported copper−indium−selenide clusters, such as [Cu 6 In 8 Se 13 Cl 4 (P n Pr 2 Ph) 12 ] (vide infra) which is prepared from mixing CuCl, InCl 3 , and Se(SiMe 3 ) 2 6a …”

“…To date the exploration of binary metal−sulfide and −selenide (ME) nanoclusters has been much more extensive in contrast to ternary (MM‘E) nanoclusters, and this may be attributed, in part, to a lack of suitable “binary” silyl reagents that can be employed to yield ternary clusters. A general molecular synthetic route to access ternary nanoclusters is desirable since ternary materials find widespread applications in optical and electronic devices.…”

Two copper-mercury-chalcogenide clusters [Hg(15)Cu(20)E(25)(PPr(3))(18)] (1, E = S; 2, E = Se) are synthesized in good yield from the reaction of (Pr(3)P)(3)Cu-ESiMe(3) and (Pr(3)P)(2).Hg(OAc)(2) at low temperatures. Single-crystal X-ray analyses illustrate that the two ternary clusters are isomorphous and consist of a phosphine-stabilized core of mixed Hg, Cu, and E centers. Thermolysis of 1 leads to the formation of mercury metal and various forms of copper-sulfide. The copper-indium-sulfide cluster [Cu(6)In(8)S(13)Cl(4)(PEt(3))(12)] (3) is similarly prepared in 50% yield from (Et(3)P)(3)Cu-SSiMe(3), InCl(3), and S(SiMe(3))(2).

“…The method of interest to our research can be depicted by eq 4, where use of the trimethylsilyl moiety allows for favorable thermodynamic release of X−SiMe 3 13 (X can be a halide, acetate, amide, or any other adequate leaving group). In this case the substituent “R” is typically an alkyl (butyl) or aryl (phenyl, mesityl) moiety. Tanaka and co-workers have illustrated recently that a terminal trimethylsilytellurolate ligand can be accessed via the oxidative addition of Te(SiMe 3 ) 2 to a Pt(0) center .…”

The copper−chalogenolates (R3P)3Cu−ESiMe3 (E = S, 1; Se, 2; Te, 3; R = Et, a; n Pr, b) have been prepared in high yield from (R3P)3CuOAc and E(SiMe3)2 at low temperatures. Complexes 1−3 contain a pendant −SiMe3 moiety bonded to a chalcogen center. These copper−chalcogenolates are clear, colorless, low-melting-point solids and have been characterized by single-crystal crystallographic and spectroscopic methods.

The reaction of [(3,5-Me(2)-C(5)H(3)N)(2)Zn(ESiMe(3))(2)] (E = Se, Te) with cadmium(II) acetate in the presence of PhESiMe(3) and P(n)Pr(3) at low temperature leads to the formation of single crystals of the ternary nanoclusters [Zn(x)()Cd(10)(-)(x)()E(4)-(EPh)(12)(P(n)()Pr(3))(4)] [E = Se, x = 1.8 (2a), 2.6 (2b); Te, x = 1.8 (3a), 2.6 (3b)] in good yield. The clusters [Zn(3)Hg(7)Se(4)(SePh)(12)(P(n)()Pr(3))(4)] (4) and [Cd(3.7)Hg(6.3)Se(4)(SePh)(12)(P(n)()Pr(3))(4)] (5) can be accessed by similar reactions involving [(3,5-Me(2)-C(5)H(3)N)(2)Zn(SeSiMe(3))(2)] or [(N,N'-tmeda)Cd(SeSiMe(3))(2)] (1) and mercury(II) chloride. The metal silylchalcogenolate reagents are efficient delivery sources of {ME(2)} in cluster synthesis, and thus, the metal ion content of these clusters can be readily moderated by controlling the reaction stoichiometry. The reaction of cadmium acetate with [(3,5-Me(2)-C(5)H(3)N)(2)Zn(SSiMe(3))(2)], PhSSiMe(3), and P(n)()Pr(3) affords the larger nanocluster [Zn(2.3)Cd(14.7)S(4)(SPh)(26)(P(n)()Pr(3))(2)] (6). The incorporation of Zn(II) into {Cd(10)E} (E = Se, Te) and Zn(II) or Cd(II) into {Hg(10)Se} nanoclusters results in a significant blue shift in the energy of the first "excitonic" transition. Solid-state thermolysis of complexes 2 and 3 reveals that these clusters can be used as single-source precursors to bulk ternary Zn(x)Cd(1)(-)(x)E materials as well as larger intermediate clusters and that the metal ion ratio is retained during these reactions.
