“…[13] The N À N bond length in this complex measures 147.5(1.4) pm and is thus close to the value expected for a NÀN single bond (in hydrazine, the NÀN bond length amounts to 145 pm). The complex can be reduced to obtain NH 3 or mixtures of NH 3 and N 2 H 4 .…”

There is ongoing interest in metal complexes which bind dinitrogen and facilitate either its reduction or oxidation under mild conditions. In nature, the enzyme nitrogenase catalyzes this process, and dinitrogen fixation occurs under mild and ambient conditions at a metal-sulfur cluster in the center of the MoFe protein, but the mechanism of this process remains largely unknown. In the last few years, new important discoveries have been made in this field. In this review are discussed recent findings on the interaction of N(2) with metal atoms and metal-atom dimers from all groups of the periodic table as provided by gas-phase as well as matrix-isolation experiments. Intrinsic dinitrogen activation at such bare metal atoms is then related to corresponding processes at complexes, clusters, and surfaces.

“…Nitrogen becomes up to pentacoordinate (15) in homoleptic [N(AuL) 5 ] 2+ while for phosphorus hexacoordinate species [P(AuL) 6 ] 3+ are reached (16). Work was also successful with polyaurated hydrazines (17) and hydroxylamines (18), amines (19), imines (20), phosphinimines (21), sulfoximines (22), and amides (23). Tetraaurated arsine has a non-classical square-pyramidal structure (24), and the corresponding phosphonium cations [P(AuL) 4 ] + are part of several more complicated aggregates (16b, 25).…”

The aurophilicity phenomenon: A decade of experimental findings, theoretical concepts and emerging applications

2000

The term 'aurophilicity' was introduced in 1989 to describe phenomena in the structural chemistry of gold which could not be readily rationalized by conventional concepts of chemical bonding. In the following decade the aurophilicity concept has been widely applied and supported by the results of many experimental as well as theoretical studies. It will be carried over into the new millennium as a continued incentive for investigations that will help in the understanding of the unique properties of gold.

Computational insights into the concomitant changes of hollow interior evolution in [SbnAunSbn]m (n=3, 4, 5, 6; m= -3, -2, -1, -2) complex

A series of novel all-metal sandwich species, [SbnAunSbn]m (n= 3, 4, 5, 6; m= -3, -2, -1, -2), are carefully designed and are systematically investigated in term of structure, bonding nature, stability, and potential application. These results show that [SbnAunSbn]m (n=3, 4, 5, 6; m= -3, -2, -1, -2), have local minimum values on their potential energy surfaces. For the Sb-Sb and Sb-Au bond, they are obviously covalent features, while in Au-Au, there is a typical aurophilic interaction. Furthermore, these species present expected stability owing to the positive dissociation energy, great Egap, ionization potential (IP), aromaticity and perfected mechanical stability. Interestingly, [Sb5Au5Sb5]- and [Sb6Au6Sb6]2- are aromatic, while both [Sb3Au3Sb3]3- and [Sb4Au4Sb4]2- possess conflicting aromaticity. And all the title species hold tube aromaticty and δ aromaticty. prediction The application suggests that the Sb site is favorable for absorbing CO in the units, and [Sb3Au3Sb3]3- is more suitable than others; CO is absorbed by the p-p interaction between the C and Sb atoms.
