Abstract

We report the total structure determination of a covalently bonded nanocluster polymer [Au7Ag9(dppf)3(CF3CO2)7BF4]n (1). This features a one-dimensional linear chain, consisting of unique molecular building blocks, Au7Ag8(dppf)3(CF3CO2)7 clusters, which are linked together by Ag–O bonds rather than Au–Au interactions or bidentate organic bridges as previously reported.

Abstract

An alkynyl-protected gold nanocluster [Au40(PhC≡C)20(dppm)4](SbF6)4 (dppm = bis(diphenylphosphino)methane) (1) has been synthesized. Single-crystal X-ray diffraction reveals that the cluster has a face-centered cubic (FCC) Au34 kernel that is made up of two Au20 units via sharing a rectangular face. Two linear PhC≡C–Au–C≡CPh staple motifs are located around the central part of the Au34 core, and four L-shaped PhC≡C–Au–P^P staple motifs are located at the four corners of the Au34 core. Cluster 1 and [Au38(PhC≡C)20(PPh3)4](CF3SO3)2 both have the FCC Au34 core, and it is found that the diphosphine ligands bringing two more Au atoms into the system have significant effects on the optical properties and stability of the clusters. The combination of a diphosphine ligand and an alkynyl ligand is helpful in generating new ligand-protected metal nanoclusters. [ABSTRACT FROM AUTHOR]

14. The transformation of polyoxometalates in the formation of intercluster compound [Ag41(α-SiW10O37)(tBuC≡C)27(CH3CN)3][β-SiW12O40].

Abstract

We report a unique intercluster compound comprising a Ag41 cage encapsulating a divacant [α-SiW10O37]10− anion and a complete [β-SiW12O40]4− anion as a counteranion. Two electro-redox centers associated with the inner and outer POM anions show interesting electrochemical behaviours, because the stable Ag41 cage acts as an electron transfer mediator.

24. [Ag70(PW9O34)2(tBuC≡C)44(H2O)2]8+: ionothermal synthesis of a silver cluster encapsulating lacunary polyoxometalate ions.

Abstract

A silver alkynyl cluster containing a Ag70 shell and two lacunary [PW9O34]9− templating ions was synthesized by an ionothermal approach. Fast core–shell electronic communication between silver(i) centers and polyoxometalates was verified via cyclic voltammetry studies in [BMIm]BF4. [ABSTRACT FROM AUTHOR]
