“…The adjacent fullerene layers in 3D packing are arranged in such a way that large fullerene squares are located above and below small fullerene squares. [47,48] and for Ag I (Et 2 dtc) hexamers and polymers are also known. [49,50] According to the best of our knowledge, a tetrameric structure is for the first time observed for Cu I (Et 2 dtc).…”

efficiently cocrystallized with fullerene molecules as tetrahedral monomers (6, 12), dimers (1, 7, 11), and tetramers (3, 4). Fullerene molecules form closely packed hexagonal and square layers in 1, 7, and 11, hexagonal and tetragonal 3D structures in 6 and 12, and island motifs in 3 and 4. Complexes 1-15 have a neutral ground state. However, the formation of the complexes with fullerenes changes the environment of paramagnetic Cu II and Mn II. The EPR spectra of 1, 2, 11, and 13 are essentially modified relative to those of pristine Cu(R 2 dtc) 2 because of a weak coordination of Cu II to fullerene

“…Crystal structures of [Au 2 (E$E) 2 ] 2þ (E ¼ chalcogen donor atom) have been described with dithiocarbamate [265][266][267][268][269][270][271], xantate [272], MNT [273][274][275], dithiophosphonate [276], dithiophosphinate [277], dithiophosphate [278,279] or trithiocarbonate [280] ligands. The gold-gold interaction in complexes shown in Figure 2.48 has been analyzed by ab initio Hartree-Fock calculations [281].…”

This chapter focuses mainly on closed shell gold(I) atoms which are found to feel attraction among themselves. This attraction is able to modify expected geometries or support one-, two-or three-dimensional arrays and also leads to interesting properties. Closed shell metal cations are expected to repel each other. Nevertheless, an important number of examples containing [d 8 -d 10 -s 2 ] interactions are known. Particularly strong evidence has been accumulated on the attraction between two or more d 10 shells. In the case of gold(I) such attraction between two or more monovalent gold(I) ions in compounds has been observed structurally for a long time. In these situations the gold centers approach each other to a distance of between 2.7 and 3.3 Å. This range includes the distance between gold atoms in gold metal and approaches, or even overlaps with the range of distances found in the few real Au-Au single bonds. Schmidbaur coined the name aurophilic attraction in 1990 and defined it as the unprecedented affinity between gold atoms even with closed-shell electronic configurations and equivalent electrical charges [1]. Since that moment, aurophilicity has become one of the hot topics in gold chemistry, at first with the aim of understanding such interaction, more recently because of the observation that it may play an important role in interesting properties, thus understanding and modulating aurophilic interactions could help to govern these properties, which include the optical behavior. Although different origins are possible for the luminescent emissions of coordination complexes, such as intraligand transitions (ILT), ligand to metal or metal to ligand charge transfer transitions (LMCT, MLCT) and metal centered (MCT) transitions, in many luminescent gold complexes the emissions have been related to the presence of aurophilic interactions.Information about aurophilicity and chemical situations in which it is observed may be found in different works that may be classified as those which analyse closed shell interactions in general [2], those focused on aurophilicity [1,3], and others which analyze the role of these interactions in coordination [4] and organometallic gold Modern Supramolecular Gold Chemistry: Gold-Metal Interactions and Applications.

“…This is in contrast to C-S and C-N (dtc) bond lengths which are undistinguishable within three standard deviations to Au2(S2CNEt2)2 [8] (average C-S and C-N (dtc) bond lengths of 1.72 and 1.34 Å respectively).…”

“…Interestingly, the Au-S bond lengths are longer than the corresponding ones for Au 2 (S 2 CNEt 2 ) 2 [8] (average bond length of 2.29 Å) where the dithiocarbamate (dtc) moiety acts as a Au(I)-Au(I)-bridging bidentate ligand. This is in contrast to C-S and C-N (dtc) bond lengths which are undistinguishable within three standard deviations to Au 2 (S 2 CNEt 2 ) 2 [8] (average C-S and C-N (dtc) bond lengths of 1.72 and 1.34 Å respectively).…”

A gold(I) complex with a triphenylphosphine and a monodentate N,N-dimethyldithiocarbamate ligand was synthesized and characterized by Raman spectroscopy and single crystal X-ray diffraction. DFT calculations (Gaussian 09, PBE1PBE/Lanl2dz) were undertaken for a single complex in the gas phase. The DFT-optimized structure and calculated Raman spectrum are in good agreement with the crystal structure and the experimental spectrum. Assignments of the Raman peaks are based on these DFT calculations. Frontier molecular orbitals were calculated and their nature is discussed.
