Structural information on nanometer-sized gold particles has been limited, due in part to the problem of preparing homogeneous material. Here we report the crystallization and x-ray structure determination of a p-mercaptobenzoic acid (p-MBA)–protected gold nanoparticle, which comprises 102 gold atoms and 44 p-MBAs. The central gold atoms are packed in a Marks decahedron, surrounded by additional layers of gold atoms in unanticipated geometries. The p-MBAs interact not only with the gold but… 

Chiral structure of thiolate-protected 28-gold-atom nanocluster determined by X-ray crystallography.

The crystal structure of a new nanocluster formulated as Au28(TBBT)20, where TBBT = 4-tert-butylbenzenethiolate, exhibits a rod-like Au20 kernel consisting of two interpenetrating cuboctahedra and was separated by chiral HPLC and characterized by circular dichroism spectroscopy.

The gold-sulfur interface at the nanoscale.

This Review discusses the recent progress from the viewpoint of theory and computations, with connections to relevant experiments in the understanding of the molecular structure of the gold-sulfur interface in these systems.

Racemization of a chiral nanoparticle evidences the flexibility of the gold-thiolate interface.

This is the first study on racemization of an intrinsically chiral gold nanocluster, Au38(SCH2CH2Ph)24, which goes along with a drastic rearrangement of its surface involving place exchange of several thiolates.

Staple motifs, initial steps in the formation of thiolate-protected gold nanoparticles: how do they form?

Ab initio molecular dynamics (AIMD) is used to monitor the trajectory of thiol protons reacting with a gold cluster, demonstrating that the staple motif forms in a multiple-pathway chemical reaction, releasing molecular hydrogen.

On the atomic structure of thiol-protected gold nanoparticles: a combined experimental and theoretical study.

Theoretical calculations using a new semiempirical potential, based on density functional theory and a bond-order Morse potential, are employed to simulate the adsorption process in a more realistic way and reveal the formation of gold adatoms on the nanoparticle surface and high surface disorder due to the strong S-Au bond.

Characterization of iron-carbonyl-protected gold clusters.

This work characterize for the first time, by means of near-infrared and Raman spectroscopy and time-dependent density functional calculations, gold clusters protected with iron-carbonyl ligands, such as {Au(22)[Fe(CO)(4)](12)}(6-) shown in the figure.

Investigating the structural evolution of thiolate protected gold clusters from first-principles.

Recent progress is highlighted in the theoretical exploration and prediction of the atomic structures of various thiolate-protected gold clusters based on the "divide-and-protect" concept in general and the "inherent structure rule" in particular.

Reversible chirality control in peptide-functionalized gold nanoparticles.

The induction of chiroptical properties in 2 nm diameter gold nanoparticles passivated with short peptides characterized by the Aib-l-Ala repetition in their sequence appears to be strongly influenced by the secondary structure assumed by the peptides when passivating the nanoparticles.



Divide and protect: capping gold nanoclusters with molecular gold-thiolate rings.

The calculated optical spectrum of this species features a large optical gap and a prominently peaked structure, correlating with experimental findings of "molecular-like spectra" of thiolate-protected 1.1 nm gold nanoparticles.

Inclusion-water-cluster in a three-dimensional superlattice of gold nanoparticles.

Three-dimensional particle crystals made of dicarboxylic thiolate-stabilized gold nanoparticles formed at an air/water interface showed that three well-resolved peaks existed from 3400 to 3550 cm-1 just falling in a region of OH stretching vibrational mode.

Chirality in bare and passivated gold nanoclusters

Detailed knowledge of the lattice structure, shape, morphology, surface structure, and bonding of bare and passivated gold clusters is fundamental to predict and understand their electronic, optical,
