TLDR
In this article, the conformation-determining attractive interaction between gold centers is presented, based on changes in conformation of the butadiene skelton, where the s-trans ground state geometry of 2,3-bis(diphenylphosphino)-1, 3-butadiene (2) is abandoned in the gold complex and the two gold atoms are brought into contact at a distance of 3.023(1) A.
Abstract
Another example of the conformation-determining attractive interaction between gold(I) centers is presented, based on changes in the conformation of the butadiene skelton. The s-trans ground state geometry of 2,3-bis(diphenylphosphino)-1,3-butadiene (2) is abandoned in the gold complex 3, and the two gold atoms are brought into contact at a distance of 3.023(1) A. The conformational change of the Ligand also occurrs at a single metal atom, where the bisphosphine acts as a difunctional chelating ligand, as demonstrated in the rhodium complex 4.

A briefing on aurophilicity.

TL;DR: There is now compelling experimental evidence for the existence of specific intra- and intermolecular bonding between seemingly closed-shell gold(I) centers (5d10) which manifests itself in all areas of gold chemistry.

Predicted ligand dependence of the Au(I)…Au(I) attraction in (XAuPH3)2

TL;DR: In this paper, the dependence of the Au attraction in the perpendicular model system (XAuPH 3 ) 2 on the substituent X was studied using 19-valence electron quasirelativistic pseudopotentials for Au.

Luminescent Gold(I) Acetylides: From Model Compounds to Polymers

TL;DR: The emission spectra of rigid-rod, conjugated polymeric complexes of gold(I) of the type [−Au−C⋮C−Ar−CµC−C µAuµL−Lµ]x, where Ar = aryl and L−L = diphosphine or bis(isocyanide) ligands are reported for the first time, along with corresponding spectra for analogous mononuclear and binuclear alkynylgold (I) model complexes as discussed by the authors.

Supramolecular assembly based on “emerging” intermolecular interactions of particular interest to coordination chemists

TL;DR: An overview of supramolecular assembly sustained by intermolecular contacts pertinent to the coordination chemistry community is presented in this paper, with comments on the nature of these interactions and information on the energy of stabilisation they impart.

Relativity and the periodic system of elements

TL;DR: In this article, the relativistic effects are defined as the difference between the case of a finite speed of light as in the world we live in and of an infinite speed of time as assumed by most theoretical chemistry.

Relativistic effects on chemical properties

TL;DR: In this article, special or anomalous chemical effects are examined in relation to periodic table trends, and the degree to which these are relativistic effects are determined, and it is noted that the degree of these effects and the introduction of 4f electrons (the usual textbook explanation of the anomalies) affect chemical behavior are of approximately equal magnitude.

Average structures of butadiene, acrolein, and glyoxal determined by gas electron diffraction and spectroscopy

TL;DR: In this paper, the electron diffraction intensities obtained in the present study and the rotational constants for several isotopic species reported in the literature have been analyzed by a least-squares method which combines them as joint observables.
